Would increasing the volume of the container for each of the following reactions cause the equilibrium to shift in the direction of products or reactants, or not change? (13.5)
a. $2 \mathrm{NH}_{3}(g) \rightleftarrows 3 \mathrm{H}_{2}(g)+\mathrm{N}_{2}(g)$
b. $\mathrm{N}_{2}(g)+\mathrm{O}_{2}(g) \rightleftarrows 2 \mathrm{NO}(g)$
c. $\mathrm{N}_{2}(g)+2 \mathrm{O}_{2}(g) \rightleftarrows 2 \mathrm{NO}_{2}(g)$
d. $4 \mathrm{NH}_{3}(g)+3 \mathrm{O}_{2}(g) \rightleftarrows 2 \mathrm{~N}_{2}(g)+6 \mathrm{H}_{2} \mathrm{O}(g)$
