Effect of a Catalyst on Reaction Rate: with a lower Ea than for the uncatalyzed reaction. This is shown as the blue path with Ea in the diagram below t a given temperature, a catalyst increases the rate of a reaction by providing a pathway E (RJ) products Reaction Coordinale Since the potential energy barrier is lower in the presence of a catalyst, a greater fraction of the molecules will have sufficient energy to react. Because the reactants and products...

1. A catalyst affects the rate of a chemical reaction by a. providing an alternate reaction pathway with a lower activation energy. b. decreasing the energy difference between the reactants and products. c. increasing the number of collisions between the reactants. d. increasing the average kinetic energy of the reactants.
