Question

what will be the order of 2NO+O2=2NO2???​

Answer 1

Answer:The rate law for 2NO(g) + O2(g) ====>2NO2(g) is rate=k[NO]^2[O2]. In addition to the mechanism, the following have been proposed:

I. 2NO(g) +O2(g) ===> 2NO2(g)

II. 2NO(g) ===> N2O2(g) [fast]

N2O2(g) +O2(g) ===> 2NO2(g) [slow]

III. 2NO(g) ===>N2(g) + O2(g) [fast]

N2(g) +2O2(g) ===> 2NO2(g) [slow]

Answer 2

Answer:

The reaction 2NO(g) + O2 (g) → 2NO2 (g) is second order in NO and first order in O2.
