Problem

For the gas-phase decomposition

\mathrm{COCl_2(g) \;\rightleftharpoons\; CO(g) + Cl_2(g)}

the equilibrium constant in terms of partial pressures is

K_p = 0.011

at 370 K. A rigid 10.0 L container at 370 K is charged with 0.400 mol of

\mathrm{COCl_2}

and no products. Calculate the equilibrium concentration (mol L

^{-1}

) of

\mathrm{COCl_2}

at 370 K.
