QUESTION:
Problem 79e
Kinetic-Molecular Theory of Gases: Effusion and Diffusion (Sections)
WF6 is one of the heaviest known gases. How much slower is the root-mean-square speed of WF6 than He at 300 K?
ANSWER:
Step 1 of 2
The root mean square velocity of a gas is given by the following expression:
..............................(1)
Here,
= The root mean square velocity.
= The universal gas constant.
= The molar mass gas
= The absolute temperature.
