Concept explainers
Interpretation: -The pressure that each gas would exert if present alone in that space is known as the partial pressure of gas.
Concept Introduction: - The total pressure of a mixture of gases which do not react chemically is the sum of the partial pressure of the component gases.Total pressure of the gaseous mixture = sum of partial pressure of each gas
Answer to Problem 34A
1) Partial pressure of
2) Partial pressure of
3) Partial pressure of
Explanation of Solution
In 1807 John Dalton put forward a generalization dealing with the pressure exerted by the mixture of two or more chemically non − reacting gases enclosed in a same vessel.
This is known as Dalton’s law of partial pressure.
Where,
According to Ideal gas equation
For calculating the total pressure
For calculating partial pressure of each gas individually.
Here, the three gases are
1) Nitrogen = 3.0 moles.
2) Oxygen = 2.0 moles
3) Carbon dioxide = 1.0 moles
Total moles (
Total Pressure = 10 atm
Temperature =
1) Partial pressure of Nitrogen
2) Partial pressure of Oxygen
3) Partial pressure of Oxygen
Therefore,
Now, we have to covert the values of partial pressure in Torr.
1atm = 760Torr
So,
1) Partial pressure of
2) Partial pressure of
3) Partial pressure of
