ChemistryEquilibriumJEE Main 2013

In reaction A + 2 B ⇌ 2C + D, initial concentration of B was 1.5 times of [A], but at equilibrium the concentrations of A and B became equal. The equilibrium constant for the reaction is :

Answer: (2)

Solution

Let [A]₀ = a, [B]₀ = 1.5a and x react: a − x = 1.5a − 2x ⇒ x = 0.5a. Equilibrium: A =
