Initially, the root mean square (rms) velocity of N 2 molecules at certain temperature is u. If this temperature is doubled and all the nitrogen molecules dissociate into nitrogen atoms, then the new rms velocity will be :
Text Solution
Verified by ExpertsThe correct answer is:
A
rms (N 2 ) = 
= 
= U …
After dissociation
rms (N) = 
= 
= 2u
