Equilibrium constant for the reaction $4 A (g) \overset{}{⇌} B (g) + 2 C (g)$ is –
Given:
$2 A (g) \overset{}{⇌} B (g) + Y (g); k c_{1} = 8$
$C (g) \overset{}{⇌} A (g) + \frac{1}{2} Y (g); k c_{2} = \frac{1}{4}$

Options:

Answer:

Solution:

$2 A (g) \overset{}{⇌} B (g) + Y (g) k c_{1} = 8$ ……. (1)
$2 A (g) + Y (g) \overset{}{⇌} 2 C (g) k c_{2} = (4)^{2} = 16$ ……. (2)
Add equation (1) and (2)
$4 A (g) + Y (g) \overset{}{⇌} B (g) + 2 C (g)$
$k_{C} = k c_{1} \times k c_{2} = 8 \times 16 = 128$
