A vessel contains a mixture of 1 mole of oxygen and 2 moles of nitrogen at 300 K. The ratio of the rotational kinetic energy permolecule to that permolecule is:
Options:
Answer:
A
Solution:
Both are diatomic with two rotational degrees of freedom, each (1)/(2)kT, so the rotational energy per molecule is kT for both. Ratio 1 : 1. A.
