Consider a 1.0 L sample of helium gas and a 1.0 L sample of argon gas, both a room temperature and atmospheric pressure.

Do the atoms in the helium sample have the same average kinetic energy as the atoms in the argon sample?

Consider a 1.0 L sample of helium gas and a 1.0 L sample of argon gas, both a room temperature and atmospheric pressure.

Do the atoms in the helium sample have the same average velocity as the atoms in the argon sample?

Consider a 1.0 L sample of helium gas and a 1.0 L sample of argon gas, both a room temperature and atmospheric pressure.

Do the argon atoms, because they are more massive, exert a greater pressure on the walls of the container? Explain.

Calculate the ratio of effusion rates for Ar and Kr.

A sample of neon effuses from a container in 76 seconds. The same amount of an unknown noble gas requries 155 seconds. Identify the second gas.

Calculate the root mean square velocity and kinetic energy of F₂, Cl_2, and Br₂ at 298 K. Rank these three halogens with respect to their rate of effusion.

Consider a 1.0 L sample of helium gas and a 1.0 L sample of argon gas, both a room temperature and atmospheric pressure.

Which gas sample has the faster rate of effusion?

Calculate the mean square root velocity and kinetic energy of F₂, Cl₂, and Br₂ at 298 K. Rank these three halogens with respect to their rate of effusion.

A sample of N₂O effuses from a container in 42 seconds. How long will it take the same amount of gaseous I₂ to effuse from the same container under identical conditions.

Use the van der Waals equation and the ideal gas equation to calculate the volume of 1000 mol of neon at a pressure of 500.0 atm and a temperature of 355.0 K. Explain why the two values are different.
