Q. At 3000 K, the equilibrium pressure of $CO_{2},\ CO$ and $O_{2}$ are 0.6, 0.4 and 0.2 atm respectively. $K_{p}$ for the reaction $2CO_{2} \rightleftharpoons 2CO + O_{2}$, is

A) 0.089
B) 0.098
C) 0.189
D) 0.198
Explanation

(a)
$K_{p} = \frac{p_{CO}^{2}p_{O_{2}}}{p_{CO_{2}}^{2}} = \frac{\lbrack 0.4\rbrack^{2} \times \lbrack 0.2\rbrack}{(0.6)^{2}} = 0.0888$
