If CO₂ 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)0.39 B)0.62 C)1.6 D)2.6

Question

Quizplus · Accepted Answer

Effusion rate is inversely proportional to the square root of the molecular weight of the gas. Molecular weight of CO₂ = (12+32+16) = 60 Molecular weight of NH₃ = (14+1+32+16) = 63 Therefore, the effusion rate of NH₃ will be √(60/63) times that of CO₂, which is approximately 1.6 times. Thus, the correct answer is C.
