The gas-phase reaction between hydrogen and iodine

proceeds with a rate constant for the forward reaction at 700°C of 138 L/mol · s and an activation energy of 165 kJ/mol.

(a) Calculate the activation energy of the reverse reaction given that

(b) Calculate the rate constant for the reverse reaction at 700°C. (Assume A in the equation is the same for both forward and reverse reactions.)

(c) Calculate the rate of the reverse reaction if the concentration of HI is 0.200 M. The reverse reaction is second-order in HI.
