For a reaction : \( 2 \mathrm{~A}(\mathrm{~s})+\mathrm{B}(\mathrm{g}) \longrightarrow 3 \mathrm{C}(l) \), standard entropy change of reaction is \( -2 \mathrm{~kJ} / \mathrm{mol}-\mathrm{K} \) and standard enthalpy of combustion of \( \mathrm{A}(\mathrm{s}), \mathrm{B}(\mathrm{g}) \) and \( \mathrm{C}(l) \) are \( -100,-60-285 \mathrm{~kJ} / \) mol respectively, then find the maximum useful work that can be obtained at \( 27^{\circ} \mathrm{C} \) and 1 bar pressure from the reaction - (in kJ/mol).
