Question

Under otherwise equivalent conditions, do more chemical reactions occur with a catalyst than without one? Why or why not?

a. Yes. Because catalysts lower the activation energy, a greater number of reactant molecules will have enough kinetic energy to complete the reaction.

b.Yes. Because catalysts lower the free energy (G) of the products, the reaction is more likely to be spontaneous.

c. No. Catalysts affect only the rate of a reaction, not the number of reactions that occur.

d. No. The number of reactions that occur is determined only by temperature and concentration of reactants, neither of which is affected by a catalyst.
