Chapter 13, Problem 38E

How will an increase in temperature affect each of the following equilibria? How will a decrease in the volume of the reaction vessel affect each?

(a) ${\text{2NH}}_3\left(g\right)\rightleftharpoons {\text{N}}_2\left(g\right)+3{\text{H}}_2\left(g\right)$ $\Delta H=92\text{kJ}$

(b) ${\text{N}}_2\left(g\right)+{\text{O}}_2\left(g\right)\rightleftharpoons 2\text{NO}\left(g\right)$ $\Delta H=181\text{kJ}$

(C) ${\text{2O}}_3\left(g\right)\rightleftharpoons 3{\text{O}}_2\left(g\right)$ $\Delta H=-585\text{kJ}$

(d) $\text{CaO}\left(s\right)+{\text{CO}}_2\left(g\right)\rightleftharpoons {\text{CaCO}}_3\left(s\right)$ $\Delta H=-176\text{kJ}$
