Q: Chemistry GCSE what is a catalyst?
If you just need the GCSE version (it gets far more complicated at A Level, you have to learn about activation energy and all this other crap) then it's just a substance that speeds up a reaction and allows it to happen quicker. but! The catalyst itself also remains unchanged at the end of the reaction (for reasons you probably don't need to know until A Level.) Remember that.
Q: What is the similarity between enzymes and general chemical catalysts?
(1) The enzyme is the same in many respects as a biocatalyst and a general catalyst, such as a small amount and a high catalytic efficiency. As with the general catalyst, the enzyme can only change the rate of chemical reaction and does not change the equilibrium of the chemical reaction It is possible to catalyze the activation of a large number of substrates in a short time and to reflect the high efficiency of enzyme catalysis.The enzyme can reduce the activation energy of the reaction (activation) (△ G) during the reaction, but the reaction rate is accelerated and the reaction time is reduced, but the equilibrium constant is not changed. (2) However, the enzyme is a biological macromolecule (1) Enzyme-catalyzed high efficiency: The catalytic effect of the catalyst can increase the reaction rate by 10 ^ 6 ~ 10 ^ 12 times, which is at least several times higher than that of the conventional catalyst. (2) The enzyme catalyst Highly specificity: including specificity of response, substrate specificity, chirality specificity, geometric specificity, etc., that an enzyme can only act on a certain class or a specific substance. Bond, ester bond, peptide bond and so on can be catalyzed by acid-base hydrolysis, but the hydrolysis of these chemical bonds are different, respectively, the corresponding glycosidase, esterase and peptidase, that is, they were specific (3) enzymatic reaction conditions are mild: enzymatic reaction is generally carried out in aqueous solution of pH = 5 ~ 8, the reaction temperature range is 20 ~ 40 ℃
Q: Which branch of chemistry or what specialty can study the catalyst
Physical chemistry: catalyst surface structure, catalytic mechanism and catalytic reaction process
Q: Can a catalyst decrease the rate of a chemical reaction? Please give an example if yes.
A catalyst is something that quickens the fee of reaction without getting used up itself. They many times try this by skill of lowering the activation skill, which additionally brings the optimal temperature down. So, to place it only, it relatively is B.
Q: What about the chemical reaction of the catalyst if there is no catalyst?
Slow response or no reaction
Q: How are the 4 characteristics of a catalyst (1. organic or inorganic 2. reusable 3. Highly specific, and 4. lowers activation energy) important in preforming life functions? please be as specific as possible, i understand that these are characteristic, i just don't understand why they're beneficial, other than the reusable and lowers activation energy one.
Organic or Inorganic - the catalyst (enzyme) must be organic to be found in the cell. Catalysts speed up chemical reactions inside a cell and must therefore be organic to be a functioning part of the cell. Reusable - There are so many reactions that catalysts are involved in that it would be a waste for the cell if a catalyst could only last one reaction, especially if there are inhibitors and competition for the active site. Catalysts must be reusable in order to keep the cell functioning. Catalysts always remain unchanged after a reaction. HIihly Specific - Catalysts are only made to catalyze one specific chemical reaction. Their active site has proteins bonded in such a way that only certain elements can enter the active site and H bond with those proteins. The fact that they are highly specific maximizes the productiveness of the cell. And it ensures that the cell only has catalysts to reactions that it needs to be completed. It also ensures that the elements are correctly bonded with eachother. If any two elements could enter the active site, there is no guarantee that the correct product will be produced. Catalysts and Enzymes must be super highly specific in order to properly function. Lowers Activation Energy - The more energy a cell has to spend to catalye a reaction, the worse it is for the cell and the less ATP is has for other reactions. Catalyts hold the substrates together so there is less energy that is needed to have the two substrates react with eachother. Activation Energy is the energy that is needed to start a reaction. So the less energy used by the cell for reactions, the better for the cell. Hope this helps
Q: the heterogenous catalyst ZSM-5 IS used to convert ?
Zeolite-based heterogeneous catalysts are used by industrial chemical companies in the interconversion of hydrocarbons and the alkylation of aromatic compounds. A very good example is the zeolite ZSM-5. This zeolite, developed by Mobil Oil, is an aluminosilicate zeolite with a high silica and low alumininum content. Its structure is based on channels with insecting tunnels. The aluminium sites are very acidic. The substitution of Al3+in place of the tetrahedral Si4+ silca requires the presence of an added postive charge. When this is H+, the acidity of the zeolite is very high. The reaction and catalysis chemistry of the ZSM-5 is due to this acidity. The ZSM-5 zeolite catalyst is used in the petroleum industry for hydrocarbon interconversion. An example use is in the isomerizations of xylene- from meta to para-xylene. The acidic zeolite promotes carbocation isomerizations. There are two suggested mechanisms for this type of isomerizations. Firstly shape may play a role. Perhaps para-xylene has a shape which allows it to diffuse rapidly through the zeolite structure, whereas as meta-xylene takes longer to pass through the zeolite and thus has more opportunity to be converted into the para-xylene. Secondly, is that the orientation of reactive intermediates within the zeolite channels favors specifically para-xylene.
Q: Explain how a catalyst may increase the rate of chemical reaction?
Lowers the activation energy of the reaction. Like a hill, it makes the hill lower so the reaction can proceed faster and at lower temps. Delta G is lowered. Meaning less energy is needed to move the reaction forward. Catalysts (enzymes) are substrate specific. only specified compounds like a right glove only fits a right hand and not the left hand.
Q: hey people i need your help about my science lab report...the question on my paper says "what function the catalyst?....please help me on this one...i would really appreciate if you leave me answers....much mahalos to all you folkss...thanks
concepts-blowing on Bandit - it converts Carbon monoxide into Carbon Dioxide (besides as emitting risky debris of Platinum, Iridium and tungsten). hang on - Carbon Dioxide - isn't that the ever so nasty greenhouse gas that we are all meant to be reducing our output of? i'm taking my cats off.
Q: Now, i am studying for my biology exam in 3 weeks time...i stumbled upon catalase, and then checked my book its catalyst...now im confused...is there a different among these 2 terms? i think..catalyst is the when a substance brings up or about a chemical reaction without using itself up and then catalase breaks down the toxic by-product of metabolism, hydrogen peroxide, into water and oxygen.Or am i wrong?please explain what is catalyst and catalase in biology or are they the same, just differently?
Catalysts and catalase are two different things, and the definitions that you listed are correct. A catalyst is something that speeds up the rate of a chemical reaction. Many chemical reactions occur naturally and do not require any energy, but they occur so slowly that they are not useful, and catalysts can be used in cases like this to speed up the process. For example iron metal exposed to oxygen and water turns to rust, but if you need a lot of rust by tomorrow, leaving a chunk of iron out in the rain is not a practical solution because it will take too long to convert all that iron metal into rust.
