At equilibrium, the concentrations of chlorine and iodine are both 0.02 mol dm^–3.

$\frac{1}{2}$ Cl₂ (g) + $\frac{1}{2}$ $I_{2}$ (g) $⇌$ $I$ Cl (g) K_c = 454

What is the concentration of iodine monochloride, $I$ Cl?

A. $\frac{454}{0.02}$

B. $454 \times 0.02$

C. $\frac{454}{0.04}$

D. $454 \times 0.04$
