Equilibrium Constant Calculation

Medium General Chemistry Chemical Equilibrium

Consider the following chemical equilibrium established in a closed container at constant temperature:

A(g) + B(g) ⇌ C(g) + D(g)

At equilibrium, the concentrations of the reactants A and B were measured to be 0.2 M and 0.4 M, respectively, while the concentrations of the products C and D were 0.1 M and 0.3 M, respectively.

Which of the following statements is true regarding the equilibrium constant (K_c) for this reaction?

Kc is equal to 0.75.

Kc is equal to 2.00.

Kc is equal to 1.25.

Kc cannot be determined without more information.
