State how the following reaction will be affected by increasing the pressure. Also mention whether the change will cause the reaction to go in a forward or backward direction.

The following two equilibria exist simultaneously in a closed vessel:
${\mathrm{PCl}}_5 \left(\mathrm{g}\right)\rightleftharpoons {\mathrm{PCl}}_3 \left(\mathrm{g}\right)+{\mathrm{Cl}}_2 \left(\mathrm{g}\right)$
${\mathrm{COCl}}_2 \left(\mathrm{g}\right)\rightleftharpoons \mathrm{CO} \left(\mathrm{g}\right)+{\mathrm{Cl}}_2 \left(\mathrm{g}\right)$

If some $\mathrm{CO}$ is added into the vessel, then after the equilibrium is attained again, concentration of
