Question

Consider the following reaction at equilibrium 2 F e 2 + ( a q ) + C u 2 + → 2 F e 3 + ( a q ) + C u When the reaction comes to equilibrium, what is the cell voltage?, 0.43 V, 1.11 V, 0.78 V, 0 V

When the equilibrium is attained in cell reaction, the cell will no longer do any electrical work, i.e., Δ G = 0 - Δ G = n E c e l l F So 0 = n E c e l l F or E c e l l = 0 .
