Chapter 8, Problem 8.57E

The gaseous reaction $\text{2HBr}\left(\text{g}\right)\rightleftarrows {\text{H}}_{\text{2}}\left(\text{g}\right)+{\text{Br}}_2\left(\text{g}\right)$ is endothermic. Tell which direction the equilibrium will shift for each of the following:

a. Some ${\text{H}}_{\text{2}}$ is added.

b. The temperature is increased.

c. Some ${\text{Br}}_2$ is removed.

d. A catalyst is added.

e. Some $\text{HBr}$ is removed.

f. The temperature is decreased, and some $\text{HBr}$ is removed.
