FAQ

High school chemistry, catalyst activation energy map

Catalytic reaction is the reaction of the first reaction with the catalyst or attached to the catalyst to form intermediates, and then further reaction to produce products and catalysts, so the amount of catalyst in theory is the same! The activation of these two processes can be reduced! So there will be two peaks! Can be simplified as a peak!

1. Catalysts can help to bring the reactants together in the correct orientation2. The chemical formula of a catalyst is written on the left hand side (reactant) side of an equation.3. Catalysts can provide a surface on which the reaction occurs.4. Catalysts increase the activation energy.5. Catalysts increase the magnitude of the equilibrium constant, thus favoring product formation.6. "Enzymes" are biochemical catalysts.7. Catalysts increase the rate of a reaction.8. Catalysts are slowly used up during the reaction and need to be replaced.

7 is definetly true

Biological enzymes and chemical catalysts of the differences in the source, nature and catalytic characteristics of the different, specific point

Catalyst catalytic reaction relative conditions higher, selectivity than biological enzymes

Can manganese dioxide do any catalyst for chemical reactions?

The catalyst is selective

Can Cuo react as a catalyst with H2O2, does its quality and chemical properties change?

Can be, please, upstairs said wrong ... ... ... ... ... ... catalyst is not not to participate in the reaction, the second is because the essence of the catalyst is to participate in the reaction to accelerate the reaction rate of conversion, the catalyst after the reaction will be regenerated, and before and after conservation, quality and Chemical properties do not change. CuO is the catalyst for H2O2 reaction, and the catalytic effect of CuO is better than Mn02!

What are the requirements for the catalyst for the chemical industry?

Generally find a few, according to the cost and cost of cost, choose cost-effective

What suitable catalysts can I use for the reaction between Hydrochloric acid and zinc metal?

catalysts are substances that alter the rate of a reaction.a suitable catalyst would be finely divided platinum.

Brief introduction of enzyme as biocatalyst and general chemical catalyst and its personality

can only change the rate of chemical reaction, do not change the equilibrium point of the chemical reaction, the enzyme itself does not change before and after the chemical reaction (3) can reduce the chemical reaction of the activation energy The
