Question:

Suppose that the activation energy for a certain reaction is 30 kJ/mol and the enthalpy of reaction is –75.0 kJ/mol. What act

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?

Answers

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
