Problem

A rigid

1.0\,\text{L}

container at

500\,\text{K}

initially contains

1.00\,\text{atm}

\text{COCl}_2(g)

and

0.50\,\text{atm}

of Ar. After the system reaches equilibrium at the same temperature, 30% of the original

\text{COCl}_2

has decomposed according to

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

What is the value of

K_p

500\,\text{K}

? a)
