Energy And Δg

Fundamental Law: The maximum electrical work $W_{ma x}$ obtainable from a cell is equal to the decrease in Gibbs free energy ( $Δ G$ ).
Equation: $W_{ma x} = n F E_{ce ll}$ .
Standard States: Under standard conditions, $Δ G^{\circ} = - W_{e l ec, ma x} = * * - n F E_{ce ll}^{\circ} * *$ .
Variables:
- $n$ : number of moles of electrons transferred.
- $F$ : Faraday constant ( $96485$ C/mol).
Spontaneity: Since $Δ G^{\circ}$ must be negative for a spontaneous reaction, $E_{ce ll}^{\circ}$ must be positive.
