Problem

The uncatalyzed forward reaction has an activation energy of

75\,\text{kJ}\cdot\text{mol}^{-1}

and the uncatalyzed reverse reaction has an activation energy of

85\,\text{kJ}\cdot\text{mol}^{-1}

. A catalyst lowers the activation energy of both directions by

30\,\text{kJ}\cdot\text{mol}^{-1}

. Determine the activation energies for the catalyzed forward and reverse reactions and state how, if at all, the equilibrium constant

K

changes at the same temperature.
