The equilibrium constant of a chemical reaction is the value of its reaction quotient at chemical equilibrium, a state approached by a dynamic chemical system after sufficient time has elapsed at which its composition has no measurable tendency towards further change.

The equilibrium depends on the following:-

Kc works with the molar concentrations in equilibrium and the expression for Kc, for this general reaction is:

Expression for Kc in this reaction is:

Hence, the correct option is:-

__[HF]²__

  [H2][F2]

Explanation:

Kc works with the molar concentrations in equilibrium and the expression for Kc, for this general reaction is:

2A(g)  + 3B (g) ⇄ 4C(g) + 5D(g)

Kc = [C]⁴ . [D]⁵ / [B]³ . [A]²

The reaction is:  H₂ (g) + F₂ (g) ⇌ 2HF(g)

Expression for Kc in this reaction is: [HF]² / [H₂] . [F₂]
