Question

What is the ratio of the diffusion rates of Cl₂ and O₂? (Rate)Cl_2/ (Rate)O₂ = A)0.45 B)0.69 C)0.47 D)1.5 E)0.67

Quizplus · Accepted Answer

The rate of diffusion of a molecule through a medium is directly proportional to the size of the molecule and inversely proportional to the square root of its molecular weight. Since ClS1U1B12S1U1B0 has a larger molecular weight than OS1U1B12S1U1B0, it will diffuse more slowly. The ratio of their diffusion rates can be calculated as follows:

(Rate)ClS1U1B12S1U1B0/(Rate)OS1U1B12S1U1B0 = sqrt(MW(OS1U1B12S1U1B0)/MW(C1U1B12S1U1B0)) = sqrt(32/58) = 0.67

Therefore, the answer is E) 0.67.
