Problem

A forward reaction is exothermic with ΔH=−55 kJ mol−1\Delta H = -55\,\text{kJ mol}^{-1} and has an activation energy of 90 kJ mol−190\,\text{kJ mol}^{-1}. Describe whether the reverse reaction is endothermic or exothermic and explain, without performing a numerical calculation, how its activation energy compares to 90 kJ mol−190\,\text{kJ mol}^{-1}.
