- Q: Will the catalyst change the reaction rate in the chemical reaction?
- Many of the catalysts are specific in varying degrees, and when added to the chemical reaction system that it can catalyze, it must change the rate of chemical reaction, and of course both positively and negatively catalyzed. Chemical reaction rate, it can not be called a catalyst.
- Q: Chemical questions: "CO2 and H2 in the catalyst conditions have a reaction, the reaction of the chemical equation is"
- CO2 + H2 = CO + H2O (conditions: catalyst, generally requires heating, and reversible)
- Q: pls give one or two catalysts that are used in the industry for example:Rhodium catalyst in a catalytic converter of a car or the Iron catalyst for making ammoniaTHANKS :)
- i will tell you the hydrogen and carbonmonixide production in indsutry they will use alumina based nickel catalyst for adsorption of gases, at high temperature it will breaks as small molecules like hydrogen, co2, co,ch4, after they will separate them using carbon molecular seives as catalyst. another catalyst for hydrogenation of double bond is copper chromate for sulphur removal from disel and petrol they will use COMOX ( copper and molybdinum catalyst ) after then pass through zinc sulfide with hydrogen gas , the sulfur will removed as a hydrogen sulfide.
- Q: a) A catalyst such as chlorophyll must be present for some reactions to take place.b) A catalyst such as chlorophyll is not one of the products of a chemical reaction.c) A catalyst such as chlorophyll is not a substance that is used or changed in a chemical reaction.
- (c) fairly catalyst varies the path of reaction or u can say mechanism of reaction in which activation ability receives decrease hence of which fruitful collisions occurred at extremely decrease temperature so greater beneficial opportunities for molecules to bypass activation complicated a catalyst is a substance that lowers the activation ability of a chemical reaction yet itself final unchanged in the process the time of the reaction
- Q: What makes an enzyme a catalyst?
- A.hydrogen peroxide. Catalase is an enzyme that functions in the decomposition of hydrogen peroxide to oxygen and water.
- 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.
- Q: What kind of compounds or elements can be used as catalysts in high school chemistry? What is the catalyst for what?
- Iron, manganese dioxide, mainly metal and its oxides.
- Q: If possible can anyone give me information on the active site, substrates, products, and the energy of activation as part of the answer?Responses greatly appreciated! Thankss! 10pts to best answer!
- To make it simple unlike the dude above me...enzymes (biological catalysts) lower the activation energy, which speeds up the reaction. EVERY reaction needs a little boost of energy--the activation energy--and enzymes lower that.
- Q: The catalyst can change the chemical reaction process, why is it wrong?
- The catalyst can change the chemical reaction rate
- Q: Can you describe at least 4 ways a catalyst can lower the activation energy of a reaction?
- To see how a catalyst accelerates the reaction, we need to look at the potential energy diagram shown below which compares the non-catalytic and the catalytic reaction. For the non-catalytic reaction, the figure is simply the familiar way to visualize the Arrhenius equation: the reaction proceeds when A and B collide with succificient energy to overcome the activation barrier. The change in Gibbs free energy between reactants, A + B, and the product P is delta G. The catalytic reaction starts by bonding of the reactants A and B to the catalyst, in a spontaneous reaction. Hence, the formation of this complex is exothermic and the free energy is lowered. There then follows the reaction between A and B while they are bound to the catalyst. This step is associated with an activation energy; however, it is significantly lower than that for the uncatalyzed reaction. Finally, the product P seperates from the catalyst in an endothermic step. The energy diagram illustrates 4 ways the catalyst works : The catalyst offers an alternative path for the reaction that is energetically more favorable The activation energy of the catalytic reaction is significantly smaller than that of the uncatalyzed reaction; hence the rate of the catalytic reaction is much larger The overall change in free energy for the catalytic reaction equals that of the uncatalyzed reaction. Hence, the catalyst does not affect the equilibrium constant for the overall reaction. A catalyst cannot change the thermodynamics of a reaction but it can change the kinetics. The catalyst accelerates both the forward and the reverse reaction to the same extent. In other words, if a catalyst accelerates the formation of product P from A and B, it will do the same for the decomposition of P into A and B.
