How does subdividing (grinding up) the reactants affect the rate of a chemical reaction? O It decreases the rate by giving the reactants the wrong orientation for reacting. O It increases the rate by lowering the energy of activation (E,). O It increases the rate by giving more molecules enough energy to react. O It decreases the rate by raising the energy of activation (E,).
