Silver ion reacts with ammonia to form a complex ion:
Ag⁺(aq) + 2 NH₃(aq) ® Ag(NH₃)²⁺(aq)
In a certain solution at equilibrium at 298 K, [Ag⁺] = [NH₃] = [Ag(NH₃)²⁺] = C. What is ∆Grxn at 298 K if [Ag⁺] = [NH₃] = [Ag(NH₃)²⁺] = 0.¹C?

Question

Silver ion reacts with ammonia to form a complex  ion:
Ag+(aq) + 2 NH3(aq) ® Ag(NH3)2+(aq)
In a certain solution at  equilibrium at 298 K, [Ag+] = [NH3] = [Ag(NH3)2+] = C. What is ∆Grxn at 298 K if [Ag+] = [NH3] = [Ag(NH3)2+] = 0.1C?
