(a) The standard free energy of activation of one reaction A is 90 kJ mol^–1 (21.5 kcal mol^–1). The standard free energy of activation of another reaction B is 75 kJ mol^–1 (17.9 kcal mol^–1). Which reaction is faster and by what factor? Assume a temperature of 298k.

(b) Estimate how much you would have to increase the temperature of the slower reaction so that it would have a rate equal to that of the faster reaction.
