Rate Law from Concentration versus Time Data

 NO2(g) + CO(g) NO(g) + CO2(g)

The rate of the above reaction depends only on the concentration of nitrogen dioxide at temperatures below 225°C.
At a temperature below 225°C the following data were obtained:

 Time(s) [NO2](mol/L) 0 0.560 1.75×103 0.507 4.38×103 0.444 6.56×103 0.403 1.31×104 0.315 2.62×104 0.219

Which of the following expressions for the rate law (either differential or integrated) are completely consistent with the above experimental data.

Yes No  -d[NO2]/dt = k[NO2]2

Yes No  d[CO2]/dt = k[NO2]

Yes No  d[CO2]/dt = k[NO2]2

Yes No  [NO2] = [NO2]0e-kt

Yes No  ln[NO2] - ln[NO2]0 = -kt

Calculate the rate constant (k).
Enter the numerical value and corresponding units.
