The standard free energy of activation of a reaction A is 90 kJ mol1 (21.5 kcal mol1 ) at 298 K. Reaction B is one million times faster than reaction A at the same temperature. The products of each reaction are 10 kJ mol1 (2.4 kcal mol1 ) more stable than the reactants. (a) What is the standard free energy of activation of reaction B? (b) Draw reaction free-energy diagrams for the two reactions showing the two values of DG to scale. (c) What is the standard free energy of activation of the reverse reaction in each case?
