Chapter 15, Problem 15.77QP

Consider the following equilibrium process.

$\begin{array}{cc}{\text{PCl}}_{\text{5}}\left(g\right)\rightleftarrows {\text{PCl}}_{\text{3}}\left(\text{g}\right){\text{+Cl}}_{\text{2}}\left(g\right)& \Delta H^{\circ }\end{array}=\text{92}\text{.5kJ/mol}$

Predict the direction of the shift in equilibrium when (a) the temperature is raised, (b) more chlorine gas is added to the reaction mixture, (c) some PCl₃ is removed from the mixture, (d) the pressure on the gases is increased, (e) a catalyst is added to the reaction mixture.
