Question

What is the equilibrium constant expression for the following reaction?

COCl2(g) = CO(g) + Cl2(g)


Keq=(COCl2)/(CO)+(Cl2)

Keq= (CO)(Cl2)/(COCl2)
Keq=(COCl2)/(CO)(Cl2)
Keq=(CO)+(Cl2)/(COCl2)

Answer 1

Answer:

Keq = [CO][Cl₂]/[COCl₂].

Explanation:

For the balanced reaction:

COCl₂(g) ⇄ CO(g) + Cl₂(g).

The equilibrium constant can be expressed as concentration equilibrium constant (Kc) or pressure equilibrium constant (Kp).

The equilibrium constant is the ratio of the product of products concentrations to the product of the reactants concentrations.

Keq = [CO][Cl₂]/[COCl].
