Does increasing the concentration of a catalyst have any effect on the rate of reaction?

Question

I thought that it wouldn't because the catalyst can only act to a certain capacity, but I am not sure.

Answer 1

Catalysts often act because of their surface area. In such a case, the more catalyst, the faster the reaction. Also powdered catalysts vs non=powdered catalysts show a change in rate.

Answer 2

Catalysts can be optimised for given reactions. The trick is to use just the right amount for the amount of product, flow rate, and operating conditions. If you are impatient, increasing the amount of catalyst can usually be counted on increasing the reaction rate. For example, the early catalytic converters on cars had lots of platinum. Modern converter use much less but do use more surface area and platinum metal mixtures to accomplish the same thing.

Answer 3

because of the fact the catalyst makes the ability of activation for reaction to ensue lots below devoid of it. increasing the concentration relies upon greater on statistical danger of encounters of reacting molecules. reducing the ability is greater efficient. The reducing of activation of power would come from a variety of things as making reactants sterically well known, immobilized greater for greater beneficial interaction, chemically changing the electrophilicity or nucleophilicity of the reactants, etc. all contributing to diminish power.

Answer 4

It certainly will, until the reaction has completed, then it doesn't matter if you add more.
