The equilibrium constant for the reaction AgBr(s) Ag+(aq) + Br- (aq) is the solubility product constant, Ksp = 7.7 10-13 at 25°C. Calculate G for the reaction when [Ag+] = 1.0 10-2 M and [Br-] = 1.0 10-3 M. Is the reaction spontaneous or nonspontaneous at these concentrations?
A) ( G = 69.1 kJ/mol, nonspontaneous)
B) ( G = -69.1 kJ/mol, spontaneous)
C) ( G = 97.5 kJ/mol, spontaneous)
D) ( G = 40.6 kJ/mol, nonspontaneous)
E) ( G = -97.5 kJ/mol, nonspontaneous)
