Question

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.

Answer 1

Answer:

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

              Reactants     Elements      Products

                     2                   N                   2

                     6                   Cl                  6

- Equilibrium constant

      K = $\frac{[NCl_{3}^{2}]}{[N_{2}][Cl_{2}]^{3}}$

-Substitution

      K = $\frac{[0.52]^{2}}{[0.15][0.25]^{3}}$

- Simplification

      K = $\frac{0.2704}{0.00234}$

- Result

       K = 115.37
