Can someoneill give you the following phase diagram shows how a catalyst affected the rate of a reaction. this graph shows two potential energy curves of a reaction as it relates to its reaction pathway. one of the curves shows the r which statement below best describes how the catalyst affected the reaction shown in this diagram? (2 points) the catalyst decreased the activation energy of the reactants. the catalyst increased the activation energy of the reactants. the catalyst increased activation energy of the products. the catalyst decreased activation energy of the products.
