Chapter 6, Problem 6.14VP

Interpretation Introduction

Interpretation: The given figure shows the mixtures of two diatomic gases (such as ${\text{N}}_2$ and ${\text{O}}_2$ ) in flasks of identical volume and at the same temperature. If the total pressure in each flask is same or not and out of four flasks the one that has the highest partial pressure of nitrogen is to be identified.

Concept introduction: According to kinetic molecular theory postulates,

• Particles present in the gas have consistent and random motion. They collide with each other or the walls of their container.
• The average kinetic energy of every gas particles is directly related to temperature. The speed of gas molecules increases with increase in temperature.
• Molecules having low molar mass will move faster than the molecules with high molar mass.
• Low or high pressure depends upon number of gas molecules collide with each other. It means pressure is directly related to number of molecules

To determine: If the total pressure in each flask is same or not and out of four flasks the one that has the highest partial pressure of nitrogen.
