Nitrogen react with chlorine to produce nitrogen trichloride. At equilibrium the concentration of each gas were found to be [N2]=0.15M, [Cl2]=0.25M, and [NCl3]=0.50M. calculate the equilibrium constant KC

1 answer

The balanced equation for the reaction is:

N2 + 3 Cl2 ⟶ 2 NCl3

The equilibrium constant (Kc) expression for this reaction is:

Kc = [NCl3]^2 / ([N2] * [Cl2]^3)

Plugging in the given concentrations:

Kc = (0.50M)^2 / (0.15M * (0.25M)^3)

Kc = 0.25M / (0.00390625M)

Kc ≈ 64

Therefore, the equilibrium constant (Kc) for this reaction is approximately 64.
