# Problem: Suppose you have two 1-L flasks, one containing N2 at STP and the other containing CH4 at STP.You may want to reference (Pages 415 - 419)Section 10.8 while completing this problem.How do these systems compare with respect to the rate of effusion through a pinhole leak?

###### FREE Expert Solution

Recall that Graham's Law of Effusion allows us to compare the rate of effusion of two gases. Graham's Law states that the rate of effusion of a gas is inversely proportional to its molar mass.

$\mathbf{rate}\mathbf{=}\frac{\mathbf{1}}{\sqrt{{\mathbf{MM}}_{\mathbf{gas}}}}$

This means that when comparing two gases:
