As the reaction proceeds between equivalent amounts of carbon monoxide and chlorine, according to the equation CO Cl2 = COCl2 at 300 K in the presence of a catalyst, the following decrease in the total pressure of the system was observed:
t, min 0 5 10 15 21
P, total, mm Hg 724 675 654 622 600
Determine the reaction order (V = const) graphically and analytically and the rate constant.
