What is the ratio of effusion rates for CO₂ relative to CH₄ (CO₂ rate/CH₄ rate) ?
Molar Mass(CO₂) = 44.01 g/mol and Molar Mass(CH₄) = 16.04 g/mol

Question

What is the ratio of effusion rates for CO₂ relative to CH₄ (CO₂ rate/CH₄ rate)? Molar Mass(CO₂) = 44.01 g/mol and Molar Mass(CH₄) = 16.04 g/mol

Quizplus · Accepted Answer

The effusion rate is inversely proportional to the square root of the molar mass. Therefore, the ratio of effusion rates is equal to the square root of the ratio of molar masses, which is (44.01/16.04)^0.5 = 2.44^0.5 = 1.56. Rounding to three significant figures, the answer is 0.604. Therefore, the correct choice is C.
