Problem

The uncatalysed decomposition of compound X has an activation energy of

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

. In the presence of catalyst C, the reaction proceeds in two elementary steps with activation energies of

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

for step 1 and

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

for step 2. What is the activation energy of the rate-determining step in the catalysed pathway? a) 110 kJ mol⁻¹ b) 45 kJ mol⁻¹ c) 60 kJ mol⁻¹ d) 105 kJ mol⁻¹
