Problem
A sealed container holds a mixture of ideal gases at 25∘C. The total pressure of the mixture is doubled by compressing the volume at constant temperature. Which of the following best describes the effect on the mole fraction of each gas in the mixture?
(a) Each mole fraction doubles.
(b) Each mole fraction decreases because the volume is reduced.
(c) Each mole fraction remains unchanged.
(d) The change in mole fractions cannot be determined without knowing the individual partial pressures.
