If 30cm3 of oxygen diffuses through a porous pot in 7 seconds, how long will it ...



Dicussion (1)

  • The rate of diffusion of a gas is proportional to the square root of the density.
    16 and 7 secs
    36 or 6 will be proportional to
    7/16 x 6
    7/4 x 6
    But volume of chlorine is twice that of oxygen. The rate of escape of chlorine is
    2/1 x 7/4 x 6/1 = 7 x 3; = 21 sec
