Problem 30E
A flask contains a mixture of neon (Ne), krypton (Kr), and radon (Rn) gases. Compare (a) the average kinetic energies of the three types of atoms and (b) the root-mean-square speeds. (?Hint?: Appendix D shows the molar mass (in g/mol) of each element under the chemical symbol for that element.)
Step-by-Step Solution:
Solution to 30E Step 1 M(Ne)=20.18g/mol M(Kr)=83.80 g/mol M(Rn)=222g/mol Average kinetic energy of molecules is 3 KE = kT 2 Thus average kinetic energy depends upon the temperature of the gas. (a) Since Neon, Krypton, and Radon are in a container with a temperature of T kelvin, the average kinetic energies of all three gases will be same. KE(Ne)=KE(Kr)=KE(Rn)
