Standard Free Energy Change

Home | General Chemistry 2 | Thermodynamics and Equilibrium | Standard Free Energy Change

What is the standard free energy change, \triangleG^\circ, for the following reaction?

Zn (s) + 2 H+^+ (aq) \longrightarrow Zn2+^{2+} (aq) + H2_2 (g), 25^\circC

Standard free energies of formation, \triangleGf_{f}^\circ are as follows: Zn (s), 0 kJ/mol; 2 H+^+ (aq), 0 kJ/mol; Zn2+^{2+} (aq), -147.1 kJ/mol; H2_2 (g), 0 kJ/mol
