The average speed of nitrogen molecule is v. if the temperature is doubled and nitrogen molecule dissociate into nitrogen atoms completely then new average speed becoems.

Answer»

v
`sqrt(2)v`
`2v`
4v

Solution :`v_(mg)=sqrt((8)/(pi)(RT)/(M))`
`N_(2)(g)rarr2N(g)`
`((v_(AVG))N)/((v_(avg))N_(2))sqrt((28xx2T)/(14xxT))=sqrt(4)=2`
`(v_(avg))_(N)=2v`
