Equilibrium constant for the reaction 4A (g) 
B (g) +2C(g) is –
Given:
2A(g) 
B(g)+Y(g);k Cl =8
C(g) 
A(g) + 
Y(g);kc 2 = 
Text Solution
Verified by ExpertsThe correct answer is:
D
128
2A(g) 
B(g)+Y(g)k C1 =8 .......(1)
2A(g)+Y(g) 
2C(g)kc 2 = (4) 2 = 16....... (2)
Add equation (1) and (2)
4A(g)+Y(g) 
B(g) + 2C(g)
k c = kc 1 x kc 2 = 8 x 16 = 128
