Question

Oxygen (one dm3 at 1 atm.) takes
two minutes to effuse through a
orifice. What will be the rate of
effusion of oxygen?​

Answer 1

The rate of effusion of oxygen is 4 / 1.

Explanation:

We are given that;

• The volume of oxygen = 1 dm3
• Atmospheric pressure =  1  atm
• Time of effusion "t" = 2 minutes

To find:

The rate of diffusion =?

Solution:

Rate of effuse of oxygen= √32g mol-1 / √2g mol-1  

Rate of effusion = √16 √1

Rate of effusion = 4  / 1

Thus the rate of effusion of oxygen is 4 / 1.
