Consider the following statements :
The mean free path of gas molecules
I. decreases with increase in concentration
II. increases with decrease in pressure at constant temperature
III. decreases with increase in molecular size
Which of the above statements are correct?

A

I , II

B

I, III

C

II, III

D

I, II, III

Text Solution

Verified by Experts

The correct Answer is:
D
Check yourself that all are correct.
► Decreases with increase in concentration – means increase in the number of molecules
► Increases with decrease in pressure at constant temperature – means increase in the volume available for gas molecules
► Decreases with increase in molecular size – means decrease in the volume available for gas molecules
