The problem asks us to solve the activation energy of the reverse reaction given the activation energy and the change in enthalpy. We can simply use the equation below to relate the enthalpy and the forward activation energy to the reverse activation energy. We will set Ea as the forward activation energy and Eb for the reverse.
