Nitrogen reacts with chlorine to produce nitrogen trichloride. At equilibrium, the concentrations of each gas are as follows: 0.15 mol of nitrogen, 0.25 mol of chlorine, and 0.52 mol of nitrogen trichloride. Write the balanced equation for the reaction and calculate the equilibrium constant.

The answer to your question is K = 115.37

Explanation:

Data

Nitrogen = N₂                          [N₂] = 0.15

Chlorine = Cl₂                          [Cl₂] = 0.25

Nitrogen trichloride = NCl₃     [NCl₃] = 0.52

Balanced chemical equation

                     N₂  +  3Cl₂  ⇒  2NCl₃
