At a certain temperature in a

5

L

vessel, 2 moles of carbon monoxide and 3 moles of chlorine were allowed to reach equilibrium according to the reaction,
CO + Cl₂

⇌

COCl₂
At equilibrium, if one mole of CO is present then equilibrium constant (K_c) for the reaction is :

Accepted Answer

	CO	+	Cl₂	$⇌$	COCl₂
Initially number of moles	2		3		0
At equilibrium number of moles	1		2		1

The equilibrium constant,

K_c =

\frac{[C O C l_{2}]}{[C O] [C l_{2}]}

=

\frac{(\frac{1}{5})}{(\frac{1}{5}) \times (\frac{2}{5})}

=

\frac{5}{2}

= 2.5
