Question
Chapter 10, Problem 21RQ
Interpretation Introduction
Interpretation:
The rate of effusion is inversely proportional to the density or molecular mass of the gas, is to be explained.
Concept Introduction:
Graham’s law explains the phenomenon of diffusion and effusion in gaseous molecules. In diffusion, the gaseous molecules are mixed with other gaseous molecules or intermingle with the molecules of air because of their random motions. Effusion is the movement of gaseous molecules from a system to vacuum, through a small hole or a narrow space.
