Problem

For the reaction

\text{CO}(g)+\text{Cl}_2(g)\rightleftharpoons\text{COCl}_2(g)

K_c = 1.5\times10^{4}

at 800 K. A vessel initially contains

[\text{CO}]=0.200\,\text{M}

[\text{Cl}_2]=0.300\,\text{M}

, and no phosgene. Which value is closest to the equilibrium concentration of COCl

_2

? a)

3.0\times10^{-1}\,\text{M}

2.0\times10^{-1}\,\text{M}

1.0\times10^{-1}\,\text{M}

4.0\times10^{-6}\,\text{M}
