Carbonyl chloride, also called phosgene, was used in World War 1 as a poisonous gas. The equilibrium concentrations for the reaction between carbon dioxide and molecular chlorine to form carbonyl chloride

CO(g) + Cl2(g) <--> CoCl2(g)

are [CO] = 1.2 x 10-2 M, [Cl2] = 0.054 M, and [CoCl2] = 0.14 M. Calculate the equilibrium constant (K).

Group of answer choices

A. K = 4.63 x 10-3

B. K = 216

C. K = 2.56

D. K = 6.23 x 102

The equilibrium constant can depict the amount of reactants that is converted into products at a given time. We know that if thus number is large and positive, then it means that the reaction would proceed to the right.

Thus, we have the equation of the reaction as; CO(g) + Cl2(g) <--> CoCl2(g) and we know that;

K = [CoCl2]/ [CO] [Cl2]

[CoCl2] = concentration of CoCl2

[CO] = concentration of CO

[Cl2] concentration of Cl2

Substituting the values into the equation;

K = 0.14/ 1.2 x 10-2 * 0.054

K = 216
