Vedclass · Accepted Answer

Gas molecules with higher molar mass have more kinetic energy at a given temperature.

Vedclass · Answer

(C) According to the kinetic molecular theory of gases,the average kinetic energy of gas molecules is directly proportional to the absolute temperature $(T)$ of the gas,given by the equation $KE_{avg} = \frac{3}{2}RT$. This implies that at a constant temperature,all gas molecules have the same average kinetic energy,regardless of their molar mass. Therefore,the statement that gas molecules with higher molar mass have more kinetic energy is incorrect.
