Question

An amount of 1 mole each of A and D is introduced in 1 L container, simultaneously the following two equilibria are established:

A ⇌ B + C; K_c = 10⁶ M

B + D ⇌ A; K_c = 10^-6 M^-1

The equilibrium concentration of A will be :

A ⇌ B + C ( K C ​ = 1 0 6 ) 1 − x x x ≈ 0 ≈ 1 M ≈ 1 M B + D ⇌ A K C ​ = 1 0 − 6 1 − x 1 − x x ≈ 1 ≈ 1 ( 1 ) ( 1 ) x ​ = 1 0 − 6 ⇒ x = 10 -6
