Chapter 8, Problem 8.52E

Use Le Chȃtelier’s principle to predict the direction of the equilibrium shift in the following equilibria when the indicated stress is applied:

a. ${\text{Ag}}^{+}\left(\text{aq}\right)+{\text{Cl}}^{-}\left(\text{aq}\right)\rightleftarrows \text{AgCl}\left(\text{s}\right)$; some ${\text{Ag}}^{+}$ is removed.

b. $2\text{HI}\left(\text{g}\right)+\text{heat}\rightleftarrows {\text{H}}_2\left(\text{g}\right)+{\text{I}}_2\left(\text{g}\right)$; the system is heated.

c. $\text{6Cu}\left(\text{s}\right)+{\text{N}}_{\text{2}}\left(\text{g}\right)+\text{heat}\rightleftarrows {\text{2Cu}}_3\text{N}\left(\text{s}\right)$; the system is cooled and some ${\text{N}}_{\text{2}}$ is removed.
