Question

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

# 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?
