Chapter 13.5, Problem 38PP

When heated, carbon monoxide reacts with water to produce carbon dioxide and hydrogen.
$\text{CO}(\text{g})+{\text{H}}_2\text{O}(g)\rightleftarrows {\text{CO}}_2(g)+{\text{H}}_2(g)+\text{ heat }$
For each of the following changes at equilibrium, indicate whether the equilibrium shifts in the direction of products, reactants, or does not change:
a. decreasing the temperature
b. adding more ${\text{H}}_2(g)$
c. removing ${\text{CO}}_2(g)$ as its forms
d. adding more ${\text{H}}_2\text{O}(g)$
e. decreasing the volume of the container
