Krypton gas is 21 times denser than helium gas at the same temperature and pressure. which gas is predicted to effuse faster
Inessa [10]
Helium gas would be the one to effuse faster as compared to krypton. This is because krypton is heavier than helium. Heavier molecules would require more energy to move so they tend to effuse slower than molecules that are lighter which will only require less energy.
