Arrange the gases according to increasing rate of diffusion at 50°C. A) NO₂

Question

Arrange the gases according to increasing rate of diffusion at 50°C. A) NO₂ < O₂ < SO₂ B) O₂ < NO₂ < SO₂ C) O₂ < SO₂ < NO₂ D) SO₂ < O₂ < NO₂ E) SO₂ < NO₂ < O₂

Quizplus · Accepted Answer

The rate of diffusion of gases is inversely proportional to their molar masses. The lighter the gas, the faster it diffuses. Among the given gases, NO₂ has the highest molar mass, followed by O₂ and then SO₂. Therefore, the order of increasing rate of diffusion will be SO₂ < NO₂ < O₂. Hence, the correct option is E.
