Chapter 12, Problem 46A

Interpretation Introduction

Interpretation:

The total pressure of mixture needs to be determined.

Concept introduction:

Dalton law states that total pressure of mixture is the sum of partial pressure of individual gas.

$P_T=P_A+P_B+P_C+\mathrm{....}$.

Answer to Problem 46A

The total pressure of the mixture is $0.99atm$.

Explanation of Solution

According to Dalton partial pressure law

$P_T=P_A+P_B$

$P_T=0.41+0.58=0.99atm$

The sum of partial pressure of individual gases is equal to total pressure of mixture, on the basis of Dalton law of partial pressure. It is applicable for non − reacting gases. Real gases do not obey Dalton’s law of partial pressure because these do not behave ideally.

Conclusion

Dalton law is applicable for non − reacting gases.
