If NO₂ and NH₃ are allowed to effuse through a porous membrane under identical conditions,the rate of effusion for NH₃ will be ________ times that of CO₂. A)0.37 B)0.61 C)1.6 D)2.7

Question

Quizplus · Accepted Answer

According to Graham's law of effusion, the rate of effusion is inversely proportional to the square root of the molar mass. The molar mass of NH₃ is 17 g/mol and that of NO₂ is 46 g/mol. Therefore, the rate of effusion of NH₃ compared to NO₂ is √(46/17) ≈ 1.6 times.
