The rate of effusion for a gas is inversely proportional to the square root of its molar mass. Therefore, the order of increasing rate of effusion for the given gases is:
1. CO2 (Molecular weight: 44.01 g/mol)
2. Ar (Molecular weight: 39.95 g/mol)
3. N2 (Molecular weight: 28.0 g/mol)
4. O (Molecular weight: 16.0 g/mol)
5. He (Molecular weight: 4.0 g/mol)
So, the slowest gas to effuse is CO2, followed by Ar, N2, O, and the fastest is He.
