\(C_5H_{12(g)} + 8O_{2(g)}  \to 5CO_{2(g)} + 6H_2O_{(l)}\)

\(\Delta G^o = [(5 × -394.4) + 6(-237.2)] - [(-8.2) + 8 × 0] \) \(= -3387\) કિ જૂલ  \(= -3387 × 10^{3} \) જૂલ 

\((i)\) \(C_5H_{12} + 10H_{2}O (l)\to 5CO_{2(g)} + 32\,H^{+}  + 32\,e^{-}\)  ( ઑક્સિડેશન )

\((ii)\)  \(8O_{2(g)} + 32H^{+}  + 32e^{-}  \to 16H_2O_{(l)} + 32H^{+}  + 32e^{-}\)  (રિડકશન )

\(n = 32\)  \(\therefore \,\Delta {G^o} =  - nF{E^o}_{cell} \)  \(\therefore \, - 3387 \times {10^3} =\) \(- 32 \times 96500 \times {E^o}_{cell}\)

\(\therefore \,\,{E^o}_{cell} = \frac{{3387 \times {{10}^3}}}{{32 \times 96500}}\,\, = \,1.0968\,V\)
