A vessel of 50 L capacity contains 0.5 mole of o, at `27^(@)C` under a pressure of 2 atm. If half of the molecules of `O_2` are removed from the vessel then rms speed of `O_2` molecules will

A

increase

B

decrease

C

not change

D

first increase then decrease

Text Solution

Verified by Experts

The correct Answer is:
C
RMS speed is independent of number of molecules , `u_(rms) = sqrt((3RT)/(M))` where , symbols have their usual meaning.
