Chemistry Equilibrium JEE Main

The equilibrium constant Kc for A(g)⇌B(g) is 1.1. Gas B will have molar concentration greater than A if:

(A)[A]=0.91
(B)[A]>0.91
(C)[A]>1
(D)At all theseCorrect

Answer: (D)

Solution

[B]/[A]=1.1 always at equilibrium, so [B]>[A] regardless of the specific value of [A].
