The reaction profile diagram for a reversible chemical reaction is shown below:
What are the values of the activation energy for the reverse reaction (Ea, reverseE_{\text{a, reverse}}Ea, reverse) and the overall enthalpy change for the forward reaction (ΔHforward\Delta H_{\text{forward}}ΔHforward)?
Ea, reverse=+320 kJ mol−1E_{\text{a, reverse}} = +320\text{ kJ mol}^{-1}Ea, reverse=+320 kJ mol−1 and ΔHforward=−90 kJ mol−1\Delta H_{\text{forward}} = -90\text{ kJ mol}^{-1}ΔHforward=−90 kJ mol−1
Ea, reverse=+230 kJ mol−1E_{\text{a, reverse}} = +230\text{ kJ mol}^{-1}Ea, reverse=+230 kJ mol−1 and ΔHforward=−90 kJ mol−1\Delta H_{\text{forward}} = -90\text{ kJ mol}^{-1}ΔHforward=−90 kJ mol−1
