Chapter 18, Problem 40E

Consider the following system at equilibrium at $350\text{ K}$: ${\text{CH}}_{\text{4}}\left(\text{g}\right){\text{ + CCl}}_{\text{4}}\left(\text{g}\right)\rightleftharpoons {\text{ 2 CH}}_{\text{2}}{\text{Cl}}_{\text{2}}\left(\text{g}\right){\text{ Δ}}_{\text{r}}\text{H}=18.8\text{ kJ}$. The production of ${\text{CH}}_{\text{2}}{\text{Cl}}_{\text{2}}\left(\text{g}\right)$ is favored by which of the following: (a) increasing the temperature; (b) increasing the pressure (by changing the volume); (c) increasing the volume; (d) adding ${\text{CH}}_{\text{2}}{\text{Cl}}_{\text{2}}$, (e) removing ${\text{CCl}}_{\text{4}}$ ?
