Characteristics of Equilibrium Constant

If CoO s + ...

Question

If $CoO (s) + H_{2} (g) ⇌ C o (s) + H_{2} O (g), K_{1} = 60$ ; $C o O (s) + C O (g) ⇌ C o (s) + C O_{2}, K_{2}$ = 180 then the equilibrium constant of the reaction $C O_{2} (g) + H_{2} (g) ⇌ C O (g) + H_{2} O (g)$ will be-

Solution

The correct option is D 0.33
the result reaction are coming then reaction 1 and opposite of reaction 2 added
$K_{3} = K_{1} \times 1 / K_{2}$
$60 \times 1 / 180$
0.33 ans
D is correct
