Q. What concentration of $CO _2$ be in equilibrium with $0.025 \,M \,CO$ at $120^{\circ} C$ for the reaction
$FeO ( s )+ CO ( g ) \rightleftharpoons Fe ( s )+ CO _2( g )$
If the value of $K_c=5.0$ ?

Equilibrium

Solution:

image
$K_c=\left[\frac{ CO _2( g )}{ CO ( g )}\right]=\frac{x}{0.025}=5.0$ (Given)
$\therefore x =0.125 \,M$
${\left[ CO _2\right]=0.125\, M }$
