Question

For a unimolecular reaction,

• A. The order and molecularity of the slowest step are equal to one
• B. Molecularity of the reaction can be zero, one or two
• C. More then one reacting species are involved in one step
• D. Moleculartiy of the reaction can be determined only experimentally.

Answer 1

Answer: (A)

The order and molecularity of the slowest step are equal to one

Answer 2

For a unimolecular reaction both order and molecularity are one in rate determining step.
