Exercise 5.52 with feedback You may want to reference (m pages 201-207) sections 5.8 and 5.9 while completing this problem. Part A A flask at room temperature contains exactly equal amounts (in moles) of nitrogen and xenon. Sort the conditions based on the gas described Drag the appropriate items to their respective bins. Reset Help Gas for which the molecules or atoms have the greatest average kinetic energy Gas that exerts the greater partial pressure Gas for which the molecules or atoms have the greatest average velocity Gas that would have a higher rate of effusion through a small hole opened in the flask. Nitrogen has the greater value Xenon has the greater value Both gases have the same value Submit My Answers Give Up vide Feedba Continue

Explanation / Answer

N2 + Xe = equal amounts

MW of N2 < MW of X2

a)

greatest average kientic energy --> NONE

since both gases have the same temperature, then each has the SAME value

b)

Gas which exerts greater aprtial pressure --> none, since this depends on molar concentraiton which is 50% and 50% for ech, fo Pnitrgoen = ¨xenone

choose both have the same vlaue

c)

higher rate of efussion through a small hole --> must be N2, since it is much smaller than Xe, and it is faster as well

d)

greatest average velocity --> must be the lighter molecule, which is N2, therefore, choose nitrogen has the higher value
