Question

At room temperature, the reaction between NO and O2 to give NO2 is fast, while that between CO and O2 is slow. It is due to :

Options

A.CO is smaller in size that  of NO
B.CO is poisonous
C.The activation energy for the reaction, 2NO + O2 → 2NO2 is less then 2CO + O2 → 2CO2.
D.None of the above

Solution

More is the activation energy less is the rate of reaction.
