question 89

Multiple Choice

What is the relationship between ΔG and the ΔG°_F for the reaction below? MgF₂(s) → Mg²⁺(aq) + 2 F^-(aq)

• A)ΔG = {ΔG°_f [Mg²⁺ (aq)] + 2 ΔG°_f [F^- (aq)] - ΔG°_f [MgF₂ (s)]} + RT ln ([Mg²⁺] [F^-]²/[MgF₂])
• B)ΔG = {ΔG°_f [Mg²⁺ (aq)] + 2 ΔG°_f [F^- (aq)] - ΔG°_f [MgF₂ (s)]} + RT ln ([Mg²⁺] [F^-])²)
• C)ΔG = {ΔG°_f [Mg²⁺ (aq)] + 2 ΔG°_f [F^- (aq)]} + RT ln ([Mg²⁺] [F^-]²)
• D)ΔG = {ΔG°_f [Mg²⁺ (aq)] + 2 ΔG°_f [F^- (aq)] - ΔG°_f [MgF₂ (s)]} + RT ln K_sp
