Chapter 13, Problem 13ALQ

Interpretation Introduction

Interpretation:

The use of Dalton’s law should be determined for the model of ideal gas and also find out the postulate of kinetic molecular theory which represents Dalton’s law.

Concept introduction: According to Dalton’s law of partial pressure, the sum of partial pressures of mixture of gases is equal to the total pressure of the gas.

${\text{P}}_{\text{t}\text{o}\text{t}\text{a}\text{l}}={\text{P}}_{\text{g}\text{a}\text{s}\text{ 1}}+{\text{P}}_{\text{g}\text{a}\text{s}\text{ 2}}+{\text{P}}_{\text{g}\text{a}\text{s}\text{ 3}}\mathrm{......}$

The ideal gas equation is as follows:

$\text{P}\text{V}=\text{n}\text{R}\text{T}$

Where,

P = Pressure in atm

V = Volume in Liter

n = moles of gas

R = Ideal gas constant

T = Temperature in Kelvin.
