84. Calculate the root mean square velocity and kinetic energy of
CO, CO2, and SO3 at 298 K. Which gas has the greatest velocity?
The greatest kinetic energy? The greatest effusion rate?
85. We separate U-235 from U-238 by fluorinating a sample of ura-
nium to form UF, (which is a gas) and then taking advantage of
the different rates of effusion and diffusion for compounds con-
taining the two isotopes. Calculate the ratio of effusion rates for
238UF6 and 235UF6. The atomic mass of U-235 is 235.054 amu
and that of U-238 is 238.051 amu.

86. Calculate the ratio of effusion rates for Ar and Kr.
87. A sample of neon effuses from a container in 76 seconds. The
same amount of an unknown noble gas requires 155 seconds.
Identify the second gas.

88. A sample of N₂O effuses from a container in 42 seconds. How
long will it take the same amount of gaseous 1₂ to effuse from
the same container under identical conditions?
89. The graph shows the distribution of molecular velocities for two
different molecules (A and B) at the same temperature. Which
molecule has the higher molar mass? Which molecule has the
higher rate of effusion?
