Q. Indicates the parts which define the difference between the activation energies for the reverse and forward reactions and equals the energy change in the reaction.

Q. The diagram above shows how the potential energy changes as reactants are converted to products for a given reaction. From the diagram, it can be concluded that the
(1) overall reaction is endothermic
(2) activation energy of the forward reaction is greater than that for the reverse reaction
(3) forward reaction is a more rapid reaction than the reverse reaction

A reaction takes place in three steps. The rate constant of the three steps are $k_{1}, k_{2}$ and $k_{3}$ respectively. The overall rate constant $k = \frac{k_{1} k_{3}}{k_{2}} .$ The energy of activation for the three steps are 40, 30 and 20 kJ respectively. Therefore:
