17- The decomposition of compound X is an elementary process that proceeds as follows: kf X(g) A(g)+ B(g) AH=+15 kilocalories k, The forward reaction is slow at room temperature but becomes rapid when a catalyst is added. (a) Draw a diagram of potential energy vs reaction coordinate for the uncatalyzed reaction. On this diagram label: (1) the axes (2) the energies of the reactants and the products (3) the energy of the activated complex (4) all significant energy differences (b) On the same diagram indicate the change or changes that result from the addition of the catalyst. Explain the role of the catalyst in changing the rate of the reaction. (c) If the temperature is increased, will the ratio kf/k, increase, remain the same, or decrease? Justify your answer with a one or two sentence explanation. [kr and k, are the specific rate constants for the forward and the reverse reactions, respectively.]
