\[Mg_{(s)}\left|Mg_{(aq)}^{2+}(0.1 M)\left\|Cl_{(aq)}^{-}(0.1 M)\right\| Cl_{2(g)(1 bar)}\right| Pt_{(s)}\] વીજ રાસાયણિક કોષ માટે નર્ન્સ્ટ સમીકરણ નીચેનામાંથી કયું સાચું છે ?

1. A \(E _{ cell }= E _{ cell }^0-\frac{0.059}{2} \log \frac{\left[ Cl ^{-}\right]^2}{\left[ Mg ^{2+}\right]}\)
2. B \(E _{\text {cell }}= E _{\text {cell }}^0-\frac{0.059}{2} \log \frac{\left[ Mg ^{2+}\right]}{\left[ Cl ^{-}\right]^2}\)
3. C \(E _{ cell }= E _{ cell }^0-\frac{0.059}{2} \log \frac{1}{\left[ Mg ^{2+}\right]\left[ Cl ^{-}\right]^2}\)
4. D \(E _{\text {cell }}= E _{\text {cell }}^0-\frac{0.059}{2} \log \left[ Mg ^{2+}\right][ Cl ]^2\)
