Chapter 14, Problem 70A

Interpretation Introduction

Interpretation: Dalton's law is to be explained.

Concept Introduction: At the same temperature, the pressure that the gas particles would exert if they occupied the whole volume of the mixture is the partial pressure.

Answer to Problem 70A

According to Dalton's law, the sum of the individual partial pressures of each gas that make up the mixture is equal to the total pressure of a non-reacting gas mixture.

Explanation of Solution

According to Dalton's law, the sum of the individual partial pressures of each gas that make up the mixture is equal to the total pressure of a non-reacting gas mixture.

The expression of Dalton's law is given as follows:

  $P_{\text{total}}=P_1+P_2+P_3+\mathrm{....}$

Where,

• $P_{\text{total}}$ is the total pressure gaseous mixture.
• $P_1,P_2$ and $P_3$ are the partial pressures.

Conclusion

According to Dalton's law, the sum of the individual partial pressures of each gas that make up the mixture is equal to the total pressure of a non-reacting gas mixture.
