At room temperature, the reaction between NO and O 2 is given N O 2 is fast, while that between CO and O 2 is slower it is due to

Options

  1. ACO is smaller in size than that of NO
  2. BCO is poisonous
  3. CThe activation energy for the reactions 2 N O + O 2 → 2 N O 2 is less then 2 C O + O 2 → 2 C O 2
  4. DNone of these

Correct answer

C. The activation energy for the reactions 2 N O + O 2 → 2 N O 2 is less then 2 C O + O 2 → 2 C O 2

Step-by-step solution

As The activation energy for the reactions 2 N O + O 2 → 2 N O 2 is less then 2 C O + O 2 → 2 C O 2 so NO reacts fast and CO reacts slowly. Rate of reaction ∝ 1 A c t i v a t i o n e n e r g y .
