Chemistry - Thermodynamics - II Question with Solution | TestHub

For a dimerization reaction,

$2\mathrm{A}\left(\mathrm{g}\right)\to {\mathrm{A}}_2\left(\mathrm{g}\right)$

at $298\mathrm{K},\Delta {\mathrm{U}}^{-}=-20{\mathrm{kJmol}}^{-1},\Delta {\mathrm{S}}^{-}=-30{\mathrm{JK}}^{-1}{\mathrm{mol}}^{-1}$,then the $\Delta {\mathrm{G}}^{-}$ will be …..J.
