Gibb's Free Energy and Spontaneity

Gibbs Energy Of Cell

Calculating the Gibbs Energy change from electrode Potentials: Using standard electrode potentials, clacu-late the standard Gibbs energy change at 25^(@)C for the following cell reaction. Strategy: To calculate DeltaG_("cell")^(@) , we use the equation DeltaG_("cell")^(@) = -nFE_("cell")^(@) , where E_("cell")^(@) is obtained by using a table of standard potentails and n can be inferred from the balanced chemical equation. The cell reaction equals the sum of the half-cell reactions after they have been multiplied by factors so that the electrons cancel in the summation. Note that n is the number of electrons involved in each half-reaction.
