Solution

The correct option is B $K_{3} = K_{1} K_{2}$
(I) $C O (g) + H_{2} O (g) ⇌ {C O}_{2} (g) + H_{2} (g)$

$K_{1} = \frac{p_{{C O}_{2}} . p_{H_{2}}}{p_{C O} . p_{H_{2} O}} \to (I)$

(II) ${C H}_{4} (g) + H_{2} O (g) ⇌ C O (g) + 3 H_{2} (g)$

$K_{2} = \frac{p_{C O} . {(p_{H_{2}})}^{3}}{p_{{C H}_{4}} . p_{H_{2} O}} \to (I I)$

(III) ${C H}_{4} (g) + 2 H_{2} O (g) ⇌ {C O}_{2} (g) + 4 H_{2} (g)$

$K_{3} = \frac{p_{{C O}_{2}} . {(p_{H_{2}})}^{4}}{p_{{C H}_{4}} . {(p_{H_{2} O})}^{2}} \to (I I I)$

$(I) \times (I I) \Rightarrow K_{1} \times K_{2} = \frac{p_{{C O}_{2}} . {(p_{H_{2}})}^{4}}{p_{{C H}_{4}} . {(p_{H_{2} O})}^{2}} = K_{3} \to (I I I)$
Option (C) is correct.
