Chemical Kinetics Question 294

Question: Units of rate constant of first and zero order reactions in terms of molarity M unit are respectively

Options:

A) sec1,M.sec1

B) sec1,M

C) M.sec1,sec1

D) M,sec1

Show Answer

Answer:

Correct Answer: A

Solution:

[a] For a zero order reaction. rate =k[A] i.e., rate =k hence unit of k=M.sec1 For a first order reaction. rate =k[A]

k=M.sec1/M=sec1
