For a reversible reaction, $\mathrm{A}\rightleftharpoons \mathrm{B}$, which one of the following statements is wrong from the given energy profile diagram?

-Activation energy of forward reaction is greater than backward reaction.

                                  ${\mathrm{E}}_{\mathrm{f}}>{\mathrm{E}}_{\mathrm{b}}$

Product level is higher than Reactant level forward reaction is endothermic.
The threshold energy is more than the activation energy of forward reaction.

                                  ${\mathrm{E}}_{\mathrm{f}}=\mathrm{H}+{\mathrm{E}}_{\mathrm{b}}$

The energy of activation of forward reaction is equal to the sum of the heat of reaction and the energy of activation of backward reaction.
