°C. Assuming ideal gas behavior, calculate the partial pressure of each gas and the total pressure of the mixture.
To calculate the partial pressure of each gas, we can use the Dalton's Law of Partial Pressures, which states that the total pressure of a mixture of ideal gases is equal to the sum of the partial pressures of each gas.
Given:
- Mixture composition: 60% hydrogen and 40% oxygen
- Total pressure: 1 atm
- Bulk gas temperature: 30°C
First, we need to convert the temperature from Celsius to Kelvin:
Bulk gas temperature = 30°C + 273.15 = 303.15 K
Let's calculate the partial pressure of hydrogen:
Partial pressure of hydrogen = 0.60 * Total pressure
Partial pressure of hydrogen = 0.60 * 1 atm = 0.60 atm
Now, let's calculate the partial pressure of oxygen:
Partial pressure of oxygen = 0.40 * Total pressure
Partial pressure of oxygen = 0.40 * 1 atm = 0.40 atm
Finally, the total pressure of the mixture is equal to the sum of the partial pressures of each gas:
Total pressure = Partial pressure of hydrogen + Partial pressure of oxygen
Total pressure = 0.60 atm + 0.40 atm = 1 atm
Therefore, the partial pressure of hydrogen is 0.60 atm, the partial pressure of oxygen is 0.40 atm, and the total pressure of the mixture is 1 atm.
To calculate the partial pressure of each gas, we can use the Dalton's Law of Partial Pressures, which states that the total pressure of a mixture of ideal gases is equal to the sum of the partial pressures of each gas.
Given:
- Mixture composition: 60% hydrogen and 40% oxygen
- Total pressure: 1 atm
- Bulk gas temperature: 30°C
First, we need to convert the temperature from Celsius to Kelvin:
Bulk gas temperature = 30°C + 273.15 = 303.15 K
Let's calculate the partial pressure of hydrogen:
Partial pressure of hydrogen = 0.60 * Total pressure
Partial pressure of hydrogen = 0.60 * 1 atm = 0.60 atm
Now, let's calculate the partial pressure of oxygen:
Partial pressure of oxygen = 0.40 * Total pressure
Partial pressure of oxygen = 0.40 * 1 atm = 0.40 atm
Finally, the total pressure of the mixture is equal to the sum of the partial pressures of each gas:
Total pressure = Partial pressure of hydrogen + Partial pressure of oxygen
Total pressure = 0.60 atm + 0.40 atm = 1 atm
Therefore, the partial pressure of hydrogen is 0.60 atm, the partial pressure of oxygen is 0.40 atm, and the total pressure of the mixture is 1 atm.
