The Equilibrium Constant for the Reaction AgBr(s) $\leftrightharpoons$ Ag⁺(aq) + Br^- (Aq) Is the Solubility Product Constant, K_sp

question 33

Multiple Choice

The equilibrium constant for the reaction AgBr(s) $\leftrightharpoons$ Ag⁺(aq) + Br^- (aq) is the solubility product constant, K_sp = 7.7 *10^-13 at 25 ^$\circ$ C. Calculate $\Delta$ 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) (\(\Delta\)G) = 69.1 kJ/mol, nonspontaneous
• B) (\(\Delta\)G) = -69.1 kJ/mol, spontaneous
• C) (\(\Delta\)G) = 97.5 kJ/mol, spontaneous
• D) (\(\Delta\)G) = 40.6 kJ/mol, nonspontaneous
• E) (\(\Delta\)G) = -97.5 kJ/mol, nonspontaneous
