Calculate the partial pressure of carbon monoxide from the following data:
$C a C O_{3} (s) Δ ⟶ C a O (s) + C O_{2} (g); K_{p} = 8 \times 10^{- 2} C O_{2} (g) + C (s) \to 2 C O (g) K_{p} = 2$

Solution

The correct option is B $0.4$
Given,
$C a C O_{3} (s) Δ ⟶ C a O (s) + C O_{2} (g); K_{p} = 8 \times 10^{- 2}$
$∴ K_{p} = P_{C O_{2}} = 8 \times 10^{- 2}$

Again for the reaction,
$C O_{2} (g) + C (s) \to 2 C O (g) K_{p} = 2$

$∴ K_{p} = \frac{P_{C O}^{2}}{P_{C O_{2}}} = 2 (given) ∴ 2 = \frac{P_{C O}^{2}}{8 \times 10^{- 2}}$
$\Rightarrow P_{C O} = 0.4$
