Chapter 7, Problem 7.59

(choose chapter or problem)

Oxygen can be converted into ozone by the action of lightning or electric sparks:

\(3 \mathrm{O}_{2}(\mathrm{~s}) \rightleftarrows 2 \mathrm{O}_{3}(\mathrm{~s})\)

For this reaction, \(\mathrm{\Delta H}=+285 \mathrm{~kJ} / \mathrm{mol}\) and \(K=2.68 \times 10^{-23}\) at 298 K.

(a) Is the reaction exothermic or endothermic?

(b) Are the reactants or the products favored at equilibrium?

(c) Explain the effect on the equilibrium of

(1) Increasing pressure by decreasing volume

(2) Increasing the concentration of \(\mathrm{O}_{2}(\mathrm{~g})\)

(3) Increasing the concentration of \(\mathrm{O}_{3}(\mathrm{~s})\)

(4) Adding a catalyst

(5) Increasing the temperature
