Question

The gas that has the slowest rate of diffusion among O2, H2, CO2 and CH4 is (A) O2 (B) H2 (C) CO2 (D) CH4

Tardigrade Admin · Accepted Answer

The rate of diffusion of gases under similar conditions of temperature and pressure is inversely proportional to the square roots of their molecular masses, i.e.
Rate of diffusion

α \frac{1}{M}

The correct increasing order of molecular masses of given gases is,

H_{2} < C H_{4} < O_{2} < C O_{2}

∴

Increasing order of rate of diffusion will be

C O_{2} < O_{2} < C H_{4} < H_{2}

Thus,

C O_{2}

has the slowest rate of diffusion.
