?The standard heat of formation of \(PI_{3}(s)\) is -24.7 kJ/mol, and the PI bond energy

Chapter 10, Problem 121

(choose chapter or problem)

The standard heat of formation of \(PI_{3}(s)\) is -24.7 kJ/mol, and the PI bond energy in this molecule is 184 kJ/mol. The standard heat of formation of P( g) is 334 kJ/mol, and that of \(I_{2}( g)\) is 62 kJ/mol. The \(I_{2}\) bond energy is 151 kJ/mol. Calculate the heat of sublimation of \(PI_{3}[PI_{3}(s) \rightarrow PI_{3}( g)]\).
