Rate of effusion of a gas depends upon :
Rate of effusion of a gas depends upon :
Open in App
Solution
The correct options are
A size of pin hole
B pressure
C molecular mass
D temperature
Effusion : When gas is confined to a container at high pressure than in the surrounding atmosphere it will escape from a small hole which is opened in the container until the pressure outside and inside have been equalised. This process is called effusion.
Graham's law of diffusion states "under the same conditions of temperature and pressure, the rates of diffusion of different gases are inversely proportional to the square roots of their molecular masses or their densities."
