Concept explainers
(a)
Interpretation: The gas with highest partial pressure in the mixture of four gases; A (purple), B (black), C (green) and D2(orange) needs to be determined.
Concept Introduction:According to Dalton’s law of partial pressure, the total pressure of a gaseous mixture is equal to the sum of partial pressures of all gaseous components. Hence, the total pressure is larger than the partial pressure of both gaseous components.
Mole fraction is the ratio of moles of substance and total moles in the solution or mixture.
(b)
Interpretation: The gas with the lowest partial pressure in the mixture of four gases; A (purple), B (black), C (green) and D2(orange) needs to be determined.
Concept Introduction: According to Dalton’s law of partial pressure, the total pressure of a gaseous mixture is equal to the sum of partial pressures of all gaseous components. Hence the total pressure is larger than the partial pressure of both gaseous components.
Mole fraction is the ratio of moles of substance and total moles in the solution or mixture.
(c)
Interpretation: The partial pressure of D2 gas needs to be determined if the total pressure if the gas mixture is 0.75 atm in the mixture of four gases; A (purple), B (black), C (green) and D2(orange).
Concept Introduction: According to Dalton’s law of partial pressure, the total pressure of a gaseous mixture is equal to the sum of partial pressures of all gaseous components. Hence, the total pressure is larger than the partial pressure of both gaseous components.
Mole fraction is the ratio of moles of substance and total moles in the solution or mixture.
