Catalysts vs. Reaction Rate

Postby Maya F 1E » Sun Mar 17, 2024 8:27 pm

Does increasing the amount of catalysts and enzymes increase the rate of a zero order reaction?

no, changing the number of catalysts or enzymes does not change the rate of a zero order reaction. the rate is independent of the concentration of the reactants in a zero order reaction

The rate of a zero-order reaction is constant regardless of the reactant concentration. This means that the rate of the reaction is only controlled by the rate constant (k), not by the concentration of reactants, therefore adding more catalyst or enzyme won't change the rate.

Increasing the amount of catalysts and enzymes may not directly impact the rate of a zero-order reaction by changing its concentration dependence, they can still influence the rate of the reaction by providing alternative pathways or lowering activation energy. It ultimately does not directly impact the concentration dependence of the reaction rate.

No, a zero-order reaction's rate is not increased by adding more catalysts or enzymes. The rate of a zero-order reaction is constant regardless of the reactant concentration. This indicates that the presence of catalysts or enzymes, as well as variations in reactant concentrations, have no effect on the reaction rate.
