Chemistry Question on Ideal gas equation
A vessel contains equal volumes of SO2 and CH4. Through a small hole the gases effused into vacuum. After 200 seconds the total volume is reduced to half. What is the ratio of SO2 and CH4 remaining in the vessel?
A
1:02
B
2:01
C
1:01
D
1:04
Answer
2:01
Explanation
Solution
According to Grahams law of diffusion, rCH4rSO2=MSO2MCH4 rCH4rSO2=6416=41=21 rSO2:rCH4=1:2 SO2 and CH4 effused in the ratio 1 : 2. So, the amount remains in the vessel will be in the ratio as SO2:CH4=2:1
