A4: 1 molar mixture of the He and CH is contained in a vessel at 20 bar pressure. Due to hole in the vessel the gas mixture leaks-out. If the composition (mole-ratio) of the mixture effusing-out initially is found to be x:1, then what is x?

Total moles ( =4+1=5 ) Total Pressure ( = ) Loban. ( P_{H E}=frac{4}{5} times 20=16 mathrm{ba} ) ( D_{a t_{4}}=20-16=mathrm{a} 4 mathrm{bar} ) ( x rightarrow text { lrate of Ebourion }) ) [ frac{R_{H E}}{R_{C H L}}=frac{P_{H E}}{P_{C H}} timesleft(frac{M_{H E}}{M_{C M}}right)^{1 / 2}=frac{16}{4} timesleft(frac{16}{4}right)^{1 / 2} ] ( = ) [ therefore quad x=8 ]
