Question

What is the ratio of the average molecular kinetic energy of uf6 to that of h2, both at 300 k

Answer 1

The average kinetic energy of the molecules is 5.66 × 10⁻²¹ J. According to Kinetic Molecular Theory, the average kinetic energy of gas molecules is a function only of temperature. The ratio of the average molecular kinetic energy of UF₆ to that of H₂ both at 300 k will be 1:1. As according to Kinetic molecular theory of gases, average kinetic energy is a function of temperature only. So, K.E. is dependent on temperature so here the ratio is 1:1.
