For the equilibrium

\(\mathrm{PH}_{3} \mathrm{BCl}_{3}(s) \rightleftharpoons \mathrm{PH}_{3}(g)+\mathrm{BCl}_{3}(g)\)

\(K_{p}=0.052\) at \(60^{\circ} \mathrm{C}\).

(a) Calculate \(K_{c}\).

(b) After 3.00 g of solid \(\mathrm{PH}_{3} \mathrm{BCl}_{3}\) is added to a closed 1.500-L vessel at \(60^{\circ} \mathrm{C}\), the vessel is charged with 0.0500 g of \(\mathrm{BCl}_{3}(\mathrm{~g})\). What is the equilibrium concentration of \(\mathrm{PH}_{3}\) ?
