Measurement of NO2 gas decomposition reaction kinetics is carried out in a closed cylinder with a
volume of 1 L. The reaction that occurs is:
2NO2(g) → 2NO(g) + 02(g)
Each experiment was started by filling the cylinder with NO2 gas until the pressure reached Po at
temperature T. The pressure in the cylinder (Pt) was recorded every 30 seconds during the reaction.
The data obtained are as follows.
