Question

Given the following value for the standard molar Gibbs free energy changes, ΔG°, at 25°C: Ag⁺(aq) + 2NH₃(l) → Ag(NH₃)₂⁺(aq); ΔG° = -41.0 kJ (mol Ag⁺)⁻¹ Ag⁺(aq) + Cl⁻(aq) → AgCl(s); ΔG° = -55.6 kJ (mol Ag⁺)⁻¹ Calculate the value for the thermodynamic equilibrium constant, K, at 25°C for the reaction AgCl(s) + 2NH₃(l) → Ag(NH₃)₂⁺(aq) + Cl⁻(aq) (R = 8.3 J K⁻¹ mol⁻¹)
