Question

The ratio of rates of diffusion of so2, o2 and ch4 is

Answer 1

Answer:

According to the law of diffusion :

Under same condition of temperature and pressure, rate of diffusion of gases is inversely proportional to square root of their masses .

Molar masses of different gases:

SO₂=64

O₂=32

CH₄= 16

Their rate of diffusion is as follows:

r_{SO_{2}}=\frac{1}{\sqrt{64}}r
