Problem: Which of the following gases diffuse more slowly than oxygen? F2, Ne, N2O, C2H2, NO, Cl2, H2S

FREE Expert Solution

We’re being asked to match the curve with the gas behavior described


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.

rate=1MMgas



Determine the molar mass of the given gases:

O2

oxygen → O
molar mass can be found in the Periodic Table
MO2 = 16.00 g/mol × 2 = 32.00 g/mol


F2 

flourine → F
molar mass can be found in the Periodic Table
MF2 = 19.00 g/mol × 2 = 38.00 g/mol

Will diffuse more slowly than oxygen.
