Assertion (A): The average translational kinetic energy per molecule of gas for various gases at the same temperature is the same.
Reason (R): At a given temperature, all molecules of a gas move with nearly the same speed.
Solution:
Average translational kinetic energy per molecule is \(\frac{3}{2}kT\), which depends only on temperature and is same for all gases. However, at a given temperature, gas molecules have a distribution of speeds, not the same speed. Assertion is true but Reason is false.
