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.
O2 (g) effuses at a rate that is __?__ times that of Br2 (g) under the same conditions. (rate of O2)/(rate of Br2)=?
