For the reaction
$\mathrm{C}{\mathrm{H}}_3\mathrm{C}\mathrm{O}\mathrm{O}\mathrm{H}\left(\mathrm{l}\right)+{\mathrm{C}}_2{\mathrm{H}}_5\left(\mathrm{l}\right)\rightleftharpoons \mathrm{C}{\mathrm{H}}_3\mathrm{C}\mathrm{O}\mathrm{O}{\mathrm{C}}_2{\mathrm{H}}_5\left(\mathrm{l}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)$
the value of equilibrium constant (K) is 4 at 298 K. The standard free energy change$(\mathrm{\Delta }\mathrm{G}°)$is equal to
