Chapter 5, Problem 77QAP
Interpretation Introduction

(a)

Interpretation:

The gas that will reach the end of the tube first needs to be determined, if both valves to bulb A and B are opened one by one.

Concept introduction:

The process by which the gas molecules escape from a region of high pressure to the region of low pressure is known as effusion.

For two gas molecules A and B, the time required for effusion is expressed as below:

time1time2=[(MM1)(MM2)]1/2

Where time1 and time2 is the time of effusion for gas 1 and 2. MM1 and MM2 is molar mass of gas A and B respectively.

Interpretation Introduction

(b)

Interpretation:

The change in the contents of the bulbs needs to be determined, if both the gases are required to each the end of the tube one by one.

Concept introduction:

Effusion is the process of escape of gas molecules from a high-pressure region to low pressure region through a pinhole. For two gas molecules A and B, the time required for effusion is expressed as below:

time1time2=[(MM1)(MM2)]1/2

Where time1 and time2 is the time of effusion for gas 1 and 2. MM1 and MM2 is molar mass of gas A and B respectively.
