27. Solving a chemistry problem

1. The formation of phosgene proceeds according to the equation: CO Cl2 → COCl2 The change in the concentration of reactants over time is shown in the table
t,min 0 12 18 24 30 42
СCO=CCl2, mol/l 0.01873 0.01794 0.01764 0.01734 0.01704 0.01644
Find the rate constant and concentration of phosgene 2 hours after the experiment, if it is known that the volume of the system does not change.
