Rate of a reaction can be expressed by A...

Rate of a reaction can be expressed by Arrhenius equation as:
`k = Ae^(-E_(a)//RT)`
In this equation, `E_(a)` represents:

A

(a) The energy above which all the colliding molecules will react

B

(b) The energy below which colliding molecules will not react

C

(c ) The total energy of the reactant molecules at a temperature `T`

D

(d) the fraction of molecules with enrgy greater than the activation energy of the reaction`

Text Solution

Verified by Experts

The correct Answer is:
b
`E` is activation energy. Thus order with respect to NO is `2`.
If `E_(a)+E_(R)=E_("Threshold enrgy")`, then only molecule may react.
