At a High Temperature,equal Concentrations of 0

Multiple Choice

At a high temperature,equal concentrations of 0.160 mol/L of H₂(g) and I₂(g) are initially present in a flask.The H₂ and I₂ react according to the balanced equation below. H₂(g) + I₂(g) 2 HI(g)
When equilibrium is reached,the concentration of H₂(g) has decreased to 0.036 mol/L.What is the equilibrium constant,K_c,for the reaction?

A) 3.4
B) 4.0
C) 12
D) 22
E) 48
