Problem
A sealed, rigid 10.0L container at 298K holds a mixture of He and Ar at a total pressure of 1.5atm. Additional He is injected so that the number of moles of He doubles while the amount of Ar remains unchanged and the temperature is held constant.
(1) Will the total pressure increase, decrease, or stay the same? Explain briefly.
(2) Will the partial pressure of Ar change? Explain briefly.
