Question

A flask at room temperature contains exactly equal amounts (in moles) of nitrogen and xenon. a. Which of the two gases exerts the greater partial pressure? b. The molecules or atoms of which gas have the greater average velocity? c. The molecules or atoms of which gas have the greater average kinetic energy? d. If a small hole were opened in the flask, which gas effuses more quickly?
