When you boil water, you aren't changing the elements. You're just making water vapor. However, when you burn paper, it becomes carbon (mostly). So physical changes will not change the substance, only chemical changes will.

What is the equilibrium constant expression for the following reaction?
Gwar [14]

Answer:

Kc = [CO][Cl₂]/[COCl].

Kp = P(CO)P(Cl₂)/P(COCl).

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.

Kc = [CO][Cl₂]/[COCl].

Kp = P(CO)P(Cl₂)/P(COCl).
