A reaction involving two different reactants can never be:

A

bimolecular reaction

B

second order reaction

C

first order reaction

D

unimolecular reaction

Text Solution

Verified by Experts

The correct Answer is:
D
There are different reactants (say A and B)
`A+Bto`product
Thus, it is a bimolecular reaction.
If `(dx)/(dt)=k[A][B]`
it is second-order reaction
if `((dx)/(dt))=k[A]`
or `=k[B]`
it is first order reaction.
Molecularity is indepent of rate, but is the sum of the reacting substances thus it cannot be unimolecular reaction.
