In a multistep reaction such as A+B →Q→C. The potential energy diagrame is shown below. What is Ea for the reaction Q→C?
For the reaction A+B→C+D ΔH=−20 kJ mol−1 . The activation energy of the forward reaction is 85kJ mol–1. The activation energy for backward reaction is
In an exothermic reaction A→B, the activation energy of reverse reaction is twice that of forward reaction. If enthalpy of the reaction is -80 kJ mol−1, the activation energy of the reverse reaction is :
