Chapter 6, Problem 45E

At 1100 K, $K_{\text{p}}=0.25$ for the following reaction:

$2{\text{SO}}_{\text{2}}\left(g\right)+{\text{O}}_{\text{2}}\left(g\right)\rightleftharpoons 2{\text{SO}}_{\text{3}}\left(g\right)$

Calculate the equilibrium partial pressures of ${\text{SO}}_{\text{2}}{\text{, O}}_{\text{2}}{\text{, and SO}}_{\text{3}}$ produced from an initial mixture in which $P_{{\text{SO}}_{\text{2}}}\text{=}{P}_{{\text{O}}_{\text{2}}}\text{=0}\text{.50 atm and}{\text{P}}_{{\text{SO}}_{\text{3}}}\text{=0}$ .
