QUESTION: Problem 56P

What is the ratio of effusion rates for the lightest gas, H2, and the heaviest known gas, UF6?

ANSWER:

Solution 56P:

Here, we are going to find out the ratio of effusion rates for both the gases H2 and UF6.

Step 1:

Effusion is a process by which a gas escapes from its container through a tiny hole into an evacuated space.

Graham’s law of effusion:

It states that the rate of effusion of a gas is inversely proportional to the square root of its molar mass.

Rate of effusion ----(1)

Where, is the molar mass.
