User: If a catalyst is used in a reaction, A. the energy of activation increases. B. different reaction products are obtained. C. the reaction rate increases. D. the reaction rate does not change

Weegy: It is letter C. the reaction rate increases. A catalyst is a substance, usually used in small amounts relative to the reactants, that modifies and increases the rate of a reaction without being consumed in the process. [ In an equilibrium reaction it speeds up the rate of forward and backward reactions. But a catalyst will not affect the final equilibrium of the reaction. ]
