The standard free energy of activation of one reaction A is 92.40 kJ mol%u20131 (22.08 kcal mol%u20131). The standard free energy of activation of another reaction B is 74.40 kJ mol%u20131 (17.78 kcal mol%u20131). Assume a temperature of 298 K and 1 M concentration.
By what factor is one reaction faster than the other?
