All the energy released from the reaction $X\to Y,{\Delta }_r{G}^0=-193{\text{kJ\hspace{0.17em}mol}}^{\text{-1}}$ is used for oxidizing $M^{+}$ as  $M^{+}\to M^{3+}+2e^{-},E^0=-0.25V$             

Under standard conditions, the number of moles of $M^{+}$ oxidized when one mole of X is converted to Y is $\left[F=96500Cmo{l}^{-1}\right]$
