Use the standard reaction enthalpies given below to determine H°rxn for the following reaction: P4 (g) + 10 Cl2 (g) –> 4 PCl5 (s)   ΔHreaction = ?

Given:

PCl5 (s) –> PCl3 (g) + Cl2 (g)   ΔHreaction = +157 kJ

P4 (g) + 6 Cl2 (g) –> 4 PCl3 (g)   ΔHreaction = -1207 kJ

Choices:

A. -1835 kJ

B. -1364 kJ

C. -1050 kJ

D. -1786 kJ

E. -2100 kJ

♦ Relevant knowledge

The enthalpy a reaction experiences, DH, is the amount of heat that is absorbed or released by a reaction at constant pressure. This number is a conditional function. This means that no matter how the products are created by the reactants the enthalpy of the reaction will remain constant. Consider the figure below. In accordance with Hess’ Law, as an effect of enthalpy shift as a function of the state the enthalpy variation for process 1 equals the total of the enthalpy change from processes 2 and 3.
