Chapter 5, Problem 5.50E

For the equilibrium

${\text{Br}}_{\text{2}}\left(\text{g}\right)\rightleftharpoons \text{2Br}\left(\text{g}\right)$

Equilibrium partial pressures at $755\text{K}$ are $p_{{\text{Br}}_{\text{2}}}=0.668\text{bar}$ and $p_{\text{Br}}=0.226\text{bar}$. If the volume of the system is suddenly doubled so that $p_{{\text{Br}}_{\text{2}}}=0.334\text{bar}$ and $p_{\text{Br}}=0.113\text{bar}$, what are the new partial pressures when equilibrium is reestablished? Is this consistent with Le Chatelier’s principle?
