In a certain physical system, there are two energy states available to a particle: the ground state with energy E₁ = 0 eV, and the excited state with energy E₂ = 1.5 eV. The system is in thermal equilibrium at a temperature T = 300 K. Calculate the Gibbs factor (also known as the Boltzmann factor) for the excited state . Give your answer to two decimal places.
The average thermal energy for a mono-atomic gas is: (kB is Boltzmann constant and T, absolute temperature) kBT kBT kBT
