∆G for the reaction AgBr(s) ⇌ Ag+(aq) + Br- (aq) is 69.9 kj/mol at 25C. What is the molar solubility of AgBr(s) at this temperature?

Expert Solution

in this question, Gibbs free energy is given but at equilibria, it should be zero...so may be by mistake it has written ...so I corrected that question ... I have taken that as a standard Gibbs free energy and then I was able to calculate the solve the question... I hope this will help u ..thank u
