Problem

At 298\,K, an elementary reaction has a forward activation energy of 80\,kJ\,mol

^{-1}

and an overall energy change of

\Delta E = -25\,\text{kJ}\,\text{mol}^{-1}

. What is the activation energy for the reverse reaction? a)

105\,\text{kJ\,mol}^{-1}

55\,\text{kJ\,mol}^{-1}

80\,\text{kJ\,mol}^{-1}

25\,\text{kJ\,mol}^{-1}
