UPSEE Solved Model Paper 4

According to graham's law of diffusion
Rate of diffusion α

1

√molecular‌mass

Molar mass of CO2 = 44g
Mlar mass of N2O = 28 + 16 = 44 g
Since, both CO2 and N2O have same molar mass.
Thus, they have same rate of diffusion at constant temperature and pressure
⇒ Balloon remains unchanged in size.
