A system has N distinguishable particles. Each particle has two non-degenerate states
with level separation of 0.15 eV. Calculate the average number of the particles in each
state when the system is in thermal equilibrium with the bath temperature of 300 K.
(3)
At thermal equilibrium ,number of particles in each state is given by,
where, ε1=energy of first state and ε2=energy of second state
and
ε =energy difference between the two states(level separation)
=0.15 eV
T=300 k
kB= Boltzmann constant
now,
ratio of no. of particles in the two states,
