Rate law for the reaction, NO_ 2(g) + CO_ (g) NO_ (g) + CO_ 2(g) is as R = k ,[ NO_2 ]^2 What is the order of reaction w.r.t. CO?

MHT CET 2025 Chemistry question

Rate law for the reaction, \mathrm{NO_{2(g)} + CO_{(g)} \rightarrow NO_{(g)} + CO_{2(g)}} is as What is the order of reaction w.r.t. CO?

(A)ZeroCorrect
(B)1
(C)1.5
(D)2

Answer: (A)

Solution

The order with respect to a reactant is the power of its concentration in the experimentally determined rate law. The given rate law contains no term for CO, i.e. . Hence the order with respect to CO is zero (the
