At STP which molecule will have maximum speed??? oxygen, nitrogen,both have same velocity?
- Old Science GuyLv 76 years agoFavorite Answer
the molar mass of O2 is 32 and of N2 is 28
at STP they have the same KE (temp is a measure of avg KE)
so from 1/2 m v^2
the lighter molecule must move faster than the heavier molecule
N2 is faster
