If the standard electrode potential for a cell

A_{\left( {aq} \right)}^{2 + } + 2{B_{\left( s \right)}} \to {A_{\left( s \right)}} + 2B_{\left( {aq} \right)}^ +

is 1.9 V, then the standard Gibbs energy for the reaction is

View answer and explanation

Correct option: C

-3.8 F J/mol

Option C is correct because the standard Gibbs energy is calculated using the formula

\Delta G = -nFE^\circ

, where n=2 and E° = 1.9 V.
