Chemical Equilibrium Involving Multiple Gases

Hard General Chemistry Chemical Equilibrium

In a closed system at equilibrium, the following reaction is occurring:

2A(g) + B(g) ⇌ C(g) + D(g)

At a certain temperature, the equilibrium constant (K_eq) for this reaction is found to be 4.0. If the initial concentrations of A, B, C, and D are 1.0 M, 2.0 M, 0.5 M, and 0.5 M respectively, what will be the equilibrium concentrations of all species when the system reaches equilibrium?

[A] = 0.5 M, [B] = 1.0 M, [C] = 1.0 M, [D] = 1.0 M

[A] = 0.0 M, [B] = 0.0 M, [C] = 1.0 M, [D] = 1.0 M

[A] = 0.75 M, [B] = 1.5 M, [C] = 0.75 M, [D] = 0.75 M

[A] = 0.5 M, [B] = 1.0 M, [C] = 0.5 M, [D] = 0.75 M
