**Question 4:** Arrange the following gases in order of increasing rate of effusion.**Gases:** C₂H₆, Ar, HCl, PH₃---**Explanation for Educational Context:**The rate of effusion of a gas is inversely proportional to the square root of its molar mass (Graham’s Law of Effusion). To arrange these gases in order of increasing rate of effusion, you need to know their molar masses:- **C₂H₆ (Ethane):** Molar mass ≈ 30.07 g/mol- **Ar (Argon):** Molar mass ≈ 39.95 g/mol- **HCl (Hydrogen Chloride):** Molar mass ≈ 36.46 g/mol- **PH₃ (Phosphine):** Molar mass ≈ 34.00 g/mol**Order of Increasing Rate of Effusion:** Ar < HCl < PH₃ < C₂H₆This order is based on the principle that lighter gases effuse faster than heavier ones.

According to Graham's law of effusion under the same condition of temperature and pressure, rate of effusion of a gas is inversely proportional to the square root of their molar mass. r α 1mAccording to the relation r α 1m, higher the molar mass lesser will be the rate of effusion. The given gases are C2H6 , Ar, HCl and PH3. Molar mass of C2H6 = 30.07 gmol-1Molar mass of Ar = 39.95 gmol-1Molar mass of HCl = 36.46 gmol-1Molar mass of PH3 = 34.00 gmol-1 The order of masses is written as, C2H6 >PH3>HCl>Ar. The order of rate of effusion, C2H6 <PH3 <HCl <Ar. Among these gases, argon will diffuse highly.

Rubber balloons filled with helium don't last as long as those filled with nitrogen or air because the helium leaks out in a day or two through tiny holes in the rubber, whereas the rate of effusion of nitrogen through the holes is much slower. If a balloon is filled with 60% helium and 40% nitrogen (by volume), what is the percentage of He in the gas leaking out through the rubber?
