Suppose that the activation energy for a certain reaction is 30 kJ/mol and the enthalpy of reaction is -75.0 kJ/mol. What activation energy is required to initiate the reverse reaction that converts the products into reactants?
delta H = Eaf - Ear
Eaf is activation energy for forward direction
Ear is activation energy for reverse direction
so,
delta H = Eaf - Ear
-75.0 KJ/mol = 30 KJ/mol - Ear
Ear = 105 KJ/mol
Answer: 105 KJ/mol
