Write the expression for the kinetic law of effective masses for the following reaction: CO (g) + Cl2 (g) → COCl2 (g)

We write down the expression for the kinetic law of mass action for the following reaction: CO (g) + Cl2 (g) → COCl2 (g).
For this we use the following formula.
v = k CAa CBb,
where v is the rate of this reaction;
k – coefficient of proportionality, which is called the rate constant of a chemical reaction;
CA is the concentration of reagent A, CB is the concentration of reagent B;
a and b – stoichiometric coefficients of this reaction equation.
Using this formula, we write the expression.
Vx.r. = k × [CO] × [Cl₂].
