Answer to Question #150116 in General Chemistry for Hannah

Question

A 10.0 L container of fixed volume contains 24.0 grams of argon gas, Ar, and 22.0 grams of fluorine gas, F​2.​
a) Calculate the total pressure, in atm, of the gas mixture in the container at 298 K.
b) The temperature of the mixture is decreased to 280 K. Calculate each of the following:
i) The mole fraction of Ar in the container.
ii) The partial pressure, in atm, of Ar in the container.
c) If a pinhole-sized leak forms in the container, and some of the gas particles effuse, will the ratio of moles of Ar to moles F​2​ increase, decrease, or stay the same? Justify your answer.
d) Indicate whether the average kinetic energy of the Ar atoms would be greater than, equal to, or the less than the average kinetic energy of the F​2​ molecules.
