Question

The mean kinetic energy of one mole of gas per degree of freedom (on the basis of kinetic theory of gases) is

• A. $\frac{1}{2}kT$
• B. $\frac{3}{2}kT$
• C. $\frac{3}{2}RT$
• D. $\frac{1}{2}RT$

Answer 1

The correct option is D $\frac{1}{2}RT$

On the bases of kinetic energy of gases, the mean kinetic energy of one mole of gas per degree of freedom is 12RT12RT
where RR is the universal gas constant.
On the basis kinetic energy of a molecule of gas per degree of freedom is 12kT12kT
where kk is the Boltzmann constant
