Chapter 6, Problem 101CP

Consider the reaction

${\text{3O}}_{\text{2}}\text{(}g\text{)}\rightleftharpoons {\text{2O}}_{\text{3}}\text{(}g\text{)}$

At 175°C and a pressure of 128 torr, an equilibriummixture of ${\text{O}}_{\text{2}}{\text{and O}}_{\text{3}}$ has a density of 0.168 g/L. Calculate $K_{\text{p}}$ for the above reaction at 175°C.
