Questions
The rms speed of oxygen is v at a particular temperature. If the temperature is doubled and oxygen molecules dissociate into oxygen atoms, the rms speed becomes [WB JEE 2015]
detailed solution
Correct option is C
The rms speed is given by vrms=3RTM⇒ vrms∝TMWhen temperature is doubled and molecules dissociate into atoms, then vrms 1vrms 2=TM2TM/2=TM4TM=T4T=12If (vrms)1 is v, then (vrms)2 will be 2v.Talk to our academic expert!
