The equalibrium constant for the reaction AgBr(s)<--> Ag^+(aq)+Br^-(aq) is the solubility product constant, Ksp=7.7x10^-13 at 25 degrees C. Calculate deltaG for the reaction when [Ag+]=6.0x10^-2 M and [Br-]=6.0x10^-3 M. Is the reaction spontaneous or nonspontaneous at these concentrations(R=8.314 J/Kmol)?
A. DeltaG= 4.95E1 kJ/mol;nonspontaneous
B. DeltaG= 8.88E1 kJ/mol;nonspontaneous
C. DeltaG= -69.1 kJ/mol;spontaneous
D. DeltaG= 1.96E1;nonspontaneous
E. DeltaG= 69.1 kJ/mol;spontaneous
