$Zn\,(s)\,\, + \,\,C{u^{2 + }}\,(aq)\, \rightleftharpoons \,Z{n^{2 + \,}}\,(aq)\, + Cu\,(s)$
At $300\,K$ is approximately $(R = 8 \,JK^{-1}\,mol^{-1},\, F = 96000\,C\,mol^{-1})$
$(A)$ $\Delta U = q + p \Delta V$
$(B)$ $\Delta G =\Delta H - T \Delta S$
$(C)$ $\Delta S =\frac{ q _{ rev }}{ T }$
$(D)$ $\Delta H =\Delta U -\Delta nRT$
