Problem

At 1000\,K the reaction

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

has

K_p = 6.5

. In a sealed vessel at this temperature the equilibrium partial pressures of

\mathrm{CO}

and

\mathrm{Cl_2}

are 0.25\,atm and 0.40\,atm, respectively. What is the equilibrium partial pressure of

\mathrm{COCl_2(g)}

? (a)

1.6\,\text{atm}

(b)

0.25\,\text{atm}

(c)

0.65\,\text{atm}

(d)

0.10\,\text{atm}
