For the reaction \( \mathrm{A}_{(\mathrm{g})} \rightleftharpoons \mathrm{B}_{(\mathrm{g})} \), the value of the equilibrium constant at \( 300 \mathrm{~K} \) and \( 1 \mathrm{~atm} \) is equal to 100.0 . The value of \( \Delta_{\mathrm{r}} \mathrm{G} \) for the reaction at \( 300 \mathrm{~K} \) and 1 atm in \( \mathrm{J} \mathrm{mol}^{-1} \) is \( -\mathrm{xR} \), where \( \mathrm{x} \) is

(Rounded off to the nearest integer)

\( \left(\mathrm{R}=8.31 \mathrm{~J} \mathrm{~mol}^{-1} \mathrm{~K}^{-1}\right. \) and \( \left.\ln 10=2.3\right) \)
