The average kinetic energy of molecules in a gas at temperature T is `1.5 KT`find the temperature at which the average kinetic energy of the molecules of hydrogen equals the binding energy of its atoms will hydrogen remain in molecles form at this temperature ? Take `k = 8.62xx 10^(-5) eVK^(-1)`

Answer

A

Explanation

We know `KE = 3/2 KT` and
`K=8.62 xx 10^-5 eV//K`
Binding Energy `=-13.6((1)/(oo)-(1)/(1))`
`=13.6eV`.
According to the question.
`1.5 KT = 13.6`
implies `1.5 xx 8.62 xx 10^-5 xx T = 13.6`
implies `T=(13.6)/(1.5 xx 8.62 xx 10^-5)`
`=1.05 xx 10^5 K`
No, it is impossible.
