Q. What concentration of $C O_{2}$ be in equilibrium with $0.025 M CO$ at $12 0^{\circ} C$ for the reaction
$F e O (s) + CO (g) ⇌ F e (s) + C O_{2} (g)$
If the value of $K_{c} = 5.0$ ?

$0.125 M$

$0.0125 M$

$1.25 M$

$12.5 M$

$K_{c} = [\frac{C O _{2} ( g )}{CO ( g )}] = \frac{x}{0.025} = 5.0$ (Given)
$∴ x = 0.125 M$
$[C O_{2}] = 0.125 M$

0.125M

0.0125M

1.25M

12.5M
