The standard free energy of activation of a reaction X is 89.4 kJ mol-1 at 298 K. Reaction Y is one million times faster than reaction X at the same temperature. The products of each reaction are 10.0 kJ mol-1 more stable than the reactants. (a) calculate the standard free energy of activation of reaction Y?(b) determine standard free energy of activation of the reverse of reaction Y?
