Question

Given the following information, determine the Keq for the following reaction: COCl2 (g) 2-way arrow CO (g) + Cl2 (g)

Substance

Concentration (M) equilibrium

CoCl2

1.8 x 10-3

CO

1.2 x 10-2

Cl2

1.2 x 10-2


a. 1.0 x 103

b. 12.5

c. 8.0 x 10-2

d. 9.6 x 10-4

Answer 1

From what I remember...
\(\sf \large K_{eq}=\frac{[CO][Cl_2]}{[COCl_2]}\)

just plug in the given values and that would be the equilibrium constant

Answer 2

\(\sf \large K_{eq}=\frac{[CO][Cl_2]}{[COCl_2]}\\\sf \large K_{eq}=\frac{[1.2 x 10^{-2}][1.2 x 10^{-2}]}{[1.8 x 10^{-3}]}\\K_{eq}=?\)
