JEE Main 2022 (25 Jun Shift 1)

Question

The relation between root mean square speed vrms  and most probable speed vp for the molar mass M of oxygen gas molecule at the temperature of 300 K will be 

Choose an option

Show full solutionCorrect option: C
Correct answer
Cvrms=32vp

Step-by-step explanation

RMS speed of O2 gas is vrms=3RTM=3RT32 and most probable speed of O2 gas is vmost probable=2RTM=2RT32.

Here temperature is same.

Thus, vrmsvmost probable=3RT322RT32=32

Hence, vrms=32vp
