Questions
A rigid container contains a mixture of one mole of nitrogen to two moles of He at . Then the ratio of rotational kinetic energy per molecule to the transational kinetic energy per He molecule is
detailed solution
Correct option is D
For N2 molecule, number of degrees of freedom for rotational motion is 2 and for He molecule, number of degrees of freedom for translational motion is 3.∴ The required ratio =2.KT23.KT2=23Talk to our academic expert!
