Refer to the graphs to compare the rate of this reaction with and without a catalyst.
which best describes the role of a catalyst in the rate of a reaction?
a. catalysts increase the activation energy required for a reaction, thus slowing the reaction rate.
b. catalysts increase the activation energy required for a reaction, thus increasing the reaction rate.
c. catalysts lower the activation energy required for a reaction, thus slowing the reaction rate.
d. catalysts lower the activation energy required for a reaction, thus increasing the reaction rate.
