Chapter 10, Problem 10.37CP

Interpretation Introduction

Interpretation:

Consider the effusion of 1:1 mixture of two gases and find out the following:

1. The gas molecule that has a higher average speed
2. The molecular weight of blue molecules if the yellow molecules have a molecular weight of 25.

Concept introduction:

Effusion is the movement of gas molecules through a small hole.
Graham’s Law states that the effusion rate of a gas or velocity is inversely proportional to the square root of the mass of its particles.

  $\begin{array}{c}velocity=\sqrt{\frac{1}{mass}}\\ v^2=\frac{1}{m}\end{array}$

To determine:

The gas having the higher average speed and the molecular weight of the blue molecules.
