Chapter 9 - Chemical Kinetics: Mechanisms

For a reaction, the value of ΔH_rxn = -20 kJ.mol^-1 and the value of the activation energy is 40 kJ.mol^-1.

What is the energy of the activation energy in the reverse direction?

See Solutions

Solution

E_a (forward reaction) = E_a (reverse reaction) + ΔH_rxn

⇒ E_a (reverse reaction) = E_a (forward reaction) - ΔH_rxn = 40 + 20 = 60 kJ.mol^-1
