Chapter 9, Problem 121E

Interpretation Introduction

To calculate: The heat of sublimation of $P{I}_3\left(s\right)$ using the following data:

The standard heat of formation of $P{I}_3\left(s\right)is–24.7\text{ kJ/mol}$.

The bond energy of $PIis184\text{ kJ/mol}$.

The standard heat of formation of $P\left(g\right)is334\text{ kJ/mol}\text{.}$

The standard heat of formation of $I_2\left(g\right)is62\text{ kJ/mol}$.

The I₂ bond energy is $151\text{ kJ/mol}.$
