and 
, respectively. Find the frequency of its collisions.

Text Solution
Verified by ExpertsThe correct answer is:
D
To determine the frequency of collisions for oxygen molecules, we use the formula for frequency:
Frequency 
where 
is the average speed of the molecules and 
is the mean free path.
Given:
Average speed 
Mean free path 
Substitute these values into the formula:
Frequency 
Therefore, the frequency of collisions is 
collisions per second.
