question 52

Multiple Choice

Given the following and that R = 8.314 J/K ?mol, determine the equilibrium constant, K, at 298K for the following reaction:
AgBr(s) ? Ag⁺(aq) + Br-(aq)
$\begin{array}{ll}\text { Substance } & \underline{\Delta}_{\mathrm{f}} \mathrm{G}^{\circ}(\mathrm{kJ} / \mathrm{mol}) \text { at } 298 \mathrm{~K} \\\hline\mathrm{Br}-(\mathrm{aq}) & -104.0 \\\mathrm{Ag}^{+}(\mathrm{aq}) & 77.12 \\\mathrm{AgBr}(\mathrm{s}) & -96.9\end{array}$

• A) \(5.3 \times 10 ^ { - 13 }\)
• B) \(5.2 \times 10 ^ { 4 }\)
• C) \(1.9 \times 10 ^ { 12 }\)
• D) \(1.9 \times 10 ^ { - 5 }\)
• E) \(1.8 \times 10 ^ { - 49 }\)
