1.	The reaction involving oxidation of nitric oxide to nitrous oxide follows the mechanism ____(a) \(\frac{-dO_2}{dt}\) = k[NO2]^2[O2](b) \(\frac{-dO_2}{dt}\) = k[NO2][O2](c) \(\frac{-dO_2}{dt}\) = k[NO2]^2[O2]^2(d) \(\frac{-dO_2}{dt}\) = k[NO2][O2]^2This question was posed to me in final exam.This interesting question is from Reducing the Size of Kinetic Models topic in portion Elements of Reaction Kinetics of Chemical Reaction Engineering
Answer» The CORRECT OPTION is (a) \(\frac{-dO_2}{dt}\) = k[NO2]^2[O2] Explanation: In the FIRST STEP, 2 molecules of NO form N2O2. Further oxidation of N2O2 is the slowest step and it is the RATE determining step.
