$A ( g )+ B ( g ) \rightleftharpoons AB ( g ) \text {. }$
The activation energy of the backward reaction exceeds that of the forward reaction by $2RT$ (in $J mol ^{-1}$ ). If the pre-exponential factor of the forward reaction is $4$ times that of the reverse reaction, the absolute value of $\Delta G ^{\ominus}$ (in $J mol ^{-1}$ ) for the reaction at $300 K$ is. . . . . (Given; $\ln (2)=0.7, RT =2500 J mol ^{-1}$ at $300 K$ and $G$ is the Gibbs energy)
