Zn             Mass: g
CuSO4          Mass: g  or Solution Volume: mL of Concentration: mol/L
ZnSO4          Mass: g
Cu             Mass: g
Heat Released: kJ

Enthalpy of Reaction

[1ΔHf(ZnSO4 (aq)) + 1ΔHf(Cu (s))] - [1ΔHf(Zn (s)) + 1ΔHf(CuSO4 (aq))]
[1(-1063.17) + 1(0)] - [1(0) + 1(-844.5)] = -218.67 kJ
-218.67 kJ     (exothermic)

Free Energy of Reaction (at 298.15 K)

From ΔGf° values:
[1ΔGf(ZnSO4 (aq)) + 1ΔGf(Cu (s))] - [1ΔGf(Zn (s)) + 1ΔGf(CuSO4 (aq))]
[1(-891.73) + 1(0)] - [1(0) + 1(-679.11)] = -212.62 kJ
-212.62 kJ     (spontaneous)

From ΔG = ΔH - TΔS:
-212.41 kJ     (spontaneous)

Equilibrium Constant, K (at 298.15 K)
