MCQ

For the following three reactions $a, b$ and $c,$ equilibrium constants are given :

$(i)\,CO(g)+ H_2O(g) \rightleftharpoons CO_2(g)+H_2(g)\,;\,K_1$

$(ii)\,CH_4(g)+H_2O(g) \rightleftharpoons CO(g)+3H_2(g)\,;\,K_2$

$(iii)\,CH_4(g) + 2H_2O(g) \rightleftharpoons CO_2(g)+ 4H_2(g)\,;\,K_3$

A
$K_1\sqrt{K_2} = K_3$
B
$K_2K_3 = K_1$
✓
$K_3=K_1\,K_2$
D
$K_3 \cdot K_2^3 = K_1^2$

✓

Answer

Correct option: C.

$K_3=K_1\,K_2$

c
Reaction $(c)$ can be obtained by adding reactions $(a)$ and $(b)$

therefore $K_{3}=K_{1} \cdot K_{2}$
