NO₂ (g) + CO (g) ? NO (g) + CO₂ (g)
Depends only on the concentration of nitrogen dioxide below at 225°C. At a temperature below 225°C, the following data were collected.
Time (s) [NO₂] (mol/L)
0 0.500
1.20 x 10³ 0.444
3.00 x 10³ 0.381
4.50 x 10³ 0.340
9.00 x 10³ 0.250
1.80 x 10⁴ 0.174
A. Determine the rate law and the value of the rate constant.
B. Calculate [NO₂] at 2.70 x 104 s after the start of the reaction.
