Question

Which of the following unit of time possessing reaction will be the fastest?Select the proper choice from the given choices.
(A) Femtosecond
(B) Nanosecond
(C) Picosecond
(D) Microsecond

Answer 1

Dear Student,

◆ Answer -

(A) Femtosecond

● Explaination -

• Rate of reaction is inversely proportional to time taken fo the reaction.
• Hence, speed of reaction decreases as the unit of time increases in magnitude.
• Therefore, reaction possessing femtosecond (smallest) in unit of its rate will be fastest.
• For example, reaction with rate 5 M/fs will be master that reaction with rate 5 M/ms.

Thanks dear. Hope this help you...
