Question

13. Consider two containers of volume 1.0 L at 298 K, as shown below. One container holds 0.10 mol N2 and the other holds 0.10 mol H2. The average kinetic energy of the nitrogen molecules is 6.2 X 10 -21 J. Assume that the N2 and the H2 exhibit ideal behavior. a. Is the pressure in the container holding the H2 less than, greater than, or equal to the pressure in the container holding the N2. Justify your answer. b. What is the average kinetic energy of the H2 molecules? c. The molecules of which gas, N2 or H2, have the greater average speed? Justify your answer. d. What change could be made that would decrease the average kinetic energy of the molecules in the container?

a.
Is the pressure in the container holding the H2 less than, greater than, or equal to the pressure in the container holding the N2.  Justify your answer.
b. What is the average kinetic energy of the H2 molecules?
c. The molecules of which gas, N2 or H2, have the greater average speed?  Justify your answer.
