We’re being asked to calculate the ratio of effusion rates of hydrogen gas (H2) and krypton gas (Kr).
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.
This means that when comparing two gases:
Find the ratio of effusion rates of hydrogen gas and krypton gas.
