- Q: High chemistry: Does the catalyst affect the heat and heat of the reaction?
- No effect
- 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: What are the catalysts for making oxygen in chemistry? (At least 8 listed)
- Manganese dioxide, iron oxide (red brick powder), copper oxide, ferrous oxide, iron oxide, activated carbon, egg shell, fresh liver, raw potato chips, etc.
- Q: in acid-catalyzed reaction,there are some books show the acid catalyst as H+ and there are some show it as H3O+ .Are they the same?
- Short=yes they are. Long version Traditionally, acids were defined to be compounds that produce H+ ions when dissoved in water (Arrhenius theory). But this definition is limited to acids that can be dissolved in water. Br?nsted-Lowry then formed a definition which states that acids are compounds which donates a protons or H+ ions. If u think about it, a H+ ion is practically a proton. a proton with no electron outer shell is far too reactive to stay in its current state. thus it will form a bond with H2O to form H3O+ Because of this, acid catalysts are supose to be H3O+ instead of H+. But since it is more convinient to use H+, the form of writing H+ remained instead....... and yes...... the scientists were lazy......
- Q: What happens to a catalyst after a chemical reaction?
- Only a catalyst? Poor catalyst. Catalysts get very little respect. Folks assume that catalysts don' do anything, yet they magically speed up a reaction without taking part in the reaction. That just isn't the case. Most chemical reactions take place in multiple steps. A catalyst can be a reactant in one step and a product in s subsequent step, thereby giving the impression that it did not react. The catalyst speeds up a chemical reaction by providing an alternate reaction pathway which has a lower activation energy. The lower activation energy means that more molecules will have the energy required to react, and the rate will be greater. So the bottom line is that the catalyst will have appeared not to have reacted, and returns to its original state.
- Q: in my 99 ram 2500 v8 5.9 that code came up, not sure what to do about it or what it could be any ideas or help with be great thanks
- Catalyst Efficiency Low Bank 1
- Q: How does active charcoal catalyze in some chemical reactions?
- Generally not, but it can be used as a catalyst carrier
- Q: how can you tell when a substance serves as a catalyst?
- It makes a reaction run faster and better AND it is not used up by the reaction
- Q: how do catalysts help in green chemistry?
- Catalysts reduce the energy barrier for reactions, meaning they require less energy to make the forward reaction go. This means less heat, light, or other energy sources are required to perform the same reaction without a catalyst. Also, by definition, a catalyst is not consumed in a reaction and can therefore be recycled many many times before replacement is necessary.
- 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.
