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. t (detik) Pt (atm) PNO2 (atm) | 0,8 | a 30 60 90 0,8 1,176 1,188 1,192 с a. Determine the partial pressure of NO2 gas after the reaction has lasted for 30, 60, and 90 seconds. The curve of 1/[NO2] against time (t) has been made to determine the rate equation for the decomposition reaction of NO2 gas. Two curves for reactions at different temperatures (460 and 477 K) are shown below:
