In any unimoelcular reaction ……. .

Options

A. only one reacting species is involved in the rate determining step
B. the order and the molecularity of slowest step are equal to one
C. the molecularity of the reaction is one and order is zero
D. both molecularity and order of the reaction are one

Answer

A, B

Explanation

Since, the reaction is an unimoleular reactions.Hence, in the slowest step i.e., in the rate determinig step the only one reacting species is involved. Therefore, order of reaction and molecularity of reaction and molecularity of reaction is equal to one.
