Chapter 16, Problem 59E

Consider the reaction:

   ${\text{Br}}_{\text{2}}\left(\text{g}\right)+\text{Cl2}\left(\text{g}\right)\rightleftharpoons \text{2 BrCI}\left(\text{g}\right){\text{ K}}_{\text{p}}=\text{1}.\text{11}\times \text{1}0{ }^{-4}\text{at 15}0\text{ K}$

A reaction mixture initially contains a Br₂ partial pressure of 755 torr and a Cl₂ partial pressure of 735 torr at 150 K. Calculate the equitibnum partial pressure of BrCl.
