Question

The rate law for the reaction \[\ce{2NO_{(g)} + O2_{(g)} -> 2NO2_{(g)}}\] is rate = k[NO]² [O₂] , then which among the following statement is correct?

पर्याय

• The reaction is first order in O₂, first order in NO and second order overall

• The reaction is second order in NO, zero order in O₂ and second order overall

• The reaction is second order in NO, first order in O₂ and third order overall

• The reaction is zero order overall

Answer 1

The reaction is second order in NO, first order in O₂ and third order overall

Explanation:

Rate = k[NO]² [O₂]

Here, x = 2, y = 1

∴ Overall order of reaction = x + y = 3
