In the first reaction, zinc displaces the hydrogen in sulfuric acid to form a compound, zinc sulfate. Since only one cation is being exchanged, this is a sing displacement reaction. The second reaction is double displacement because both reactants exchange anions in the product.

17.2: The Gibbs Free Energy and Cell Voltage - Chemistry LibreTexts We can now calculate ΔG° using Equation 17.2.7. Because six electrons are transferred in the overall reaction, the value of n is 6: ΔG ∘ = − (n)(F)(E ∘ cell) = − (6 mole)[96, 485 J / (V ⋅ mol)(0.27 V)] = − 15.6 × 104 J = − 156 kJ / mol Cr2O2 − 7 Thus ΔGo is −168 kJ/mol for the reaction as written, and the reaction is spontaneous.
