Chapter 13.5, Problem 35PP

In the lower atmosphere, oxygen is converted to ozone $\left({\text{O}}_3\right)$ by the energy provided from lightning.
$3{\text{O}}_2(g)+\text{ heat }\rightleftarrows 2{\text{O}}_3(g)$
For each of the following changes at equilibrium, indicate whether the equilibrium shifts in the direction of product, reactants, or does not change:
a. adding more ${\text{O}}_2(g)$
b. adding more ${\text{O}}_3(g)$
c. increasing the temperature
d. increasing the volume of the container
e. adding a catalyst
