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 Ksp
