Partial Pressure, Ideal Gases and Partial Pressure, Dalton՚s Law, Questions
Questions
To a Tank Containing at and at , We Add an Anonymous Quantity of up Until the Total Pressure Inside the Tank is . What is S Partial Pressure?
Answer:
Dalton՚s law states that the addition of does not upset the partial pressures of the and already existing in the tank. The partial pressure of and remain at , respectively, and their total is 3.0 atm. The partial pressure of the added must be if the new pressure is , Therefore, when the final pressure is , the partial pressures are
A Mixture of Hydrogen Gas and Oxygen Gas Exerts a Total Pressure of on the Walls of Its Container. If the Partial Pressure of Hydrogen is , Find the Mole Fraction of Oxygen in the Mixture
Answer:
- Given,
- Applying Dalton՚s law formula,
- Therefore,
- Now, the mole fraction of oxygen,
Therefore, the mole fraction of oxygen in the mixture is
At a Temperature of , of Gas a Kept under Pressure of and of Gas B Kept under Pressure of is Transferred into an Empty Container. Calculate the Total Pressure Inside the Container and the Partial Pressures of Gas a and Gas B (Assume That a and B Are Ideal Gases)
Answer:
- From the ideal gas equation,
- Number of moles of gas A
Number of moles of gas B
- Total number of moles in the gaseous mixture
- Total pressure inside the 10 L container
- Therefore, the total pressure inside the 10-litre container is .
- Mole fraction of gas A Mole fraction of gas B
- Therefore, partial pressure of gas A Therefore, partial pressure of gas B
- Thus, the partial pressures of gases A and B in the container are both equal to .
