Consider a cell consisting of $\mathrm {Zn(s) ~ |Zn^{2+} (1.00 × 105M)| |Ag^+~(0.10M)|Ag(s)}$ and standard reduction potentials of the cell are $\mathrm {E^\circ_{~Zn(red)} = -~0.76V}$ and $\mathrm {E^\circ_{~Ag(red)} = ~0.80 ~ V}$ at $\mathrm {25^°C.}$ For this cell the following parameters age given, $\text {i. The cell reaction is} \mathrm {~ Zn(s) + 2Ag^+(aq) → Zn^{~2+} (aq) + 2Ag(s).}$$\text {ii. }\mathrm {E_{cell} = 1.647V.}$$\text {iii. } \mathrm {\triangle G^\circ = -3.178 × 10^5~J.}$
