Choose the correct relation between standard free energy change and standard cell potential

Options

A. `Delta G^(@)= nF E_("cell")^(@)`
B. `Delta G^(@)= (nF)/(E_("cell")^(@))`
C. `Delta G^(@)= - nF E_("cell")^(@)`
D. `E_("cell")^(@) = - nFG^(@)`

Answer

C

Explanation

`Delta G^(@)= -nF E_("cell")^(@)` where n is number of moles of electrons taking part in the cell reactions, F is Faraday constant
