Question 35 (1 point) The relationship between the activation energy of the forward and reverse reactions is related by the energy difference between the reactants and products. If the reactants are higher in energy than the products, the activation energy for the forward reaction will be smaller than the activation energy for the reverse reaction and vice versa True False Question 36 (1 point) A catalyst is a substance that is not used up during a reaction. It also does...
