NH3 SO2 Cl2 CO2

Answer 1

11th/Chemistry

States of Matter

Answer :

★ Graham's law of diffusion : Under similar conditions of temperature and pressure, rates of diffusion of different gases are inversely proportional to the square root of their molar masses $.$

• r ∝ 1/√M

Molar mass of NH₃ = 17g/mol

Molar mass of SO₂ = 64g/mol

Molar mass of Cl₂ = 34g/mol

Molar mass of CO₂ = 44g/mol

➤ Order of molar masses :

• SO₂ > CO₂ > Cl₂ > NH₃

➤ Order of diffusion rate :

• NH₃ > Cl₂ > CO₂ > SO₂
