Question $6$: boltzmann$\_$v$1$

An electron is trapped using lasers $($you don't need to know details about this!$).$ All you need to know is that the electron has $3$ states, with energies as follows:

State $1$: $6\mathrm{.}1$ eV

State $2$: $6\mathrm{.}3$ eV

State $3$: $6\mathrm{.}5$ eV

It is in equilibrium with a reservoir at temperature $853$ K$.$
