At a given temperature, an atom can access three states: , , and , with energies , , and , respectively. What is the fraction of atoms in the state?
1
\(\frac{3e^{-0.3}}{2 + 3e^{-0.3} + 3e^{-0.6}}\)
2
\(\frac{3e^{-0.3}}{2 + 3e^{-0.3} + e^{-0.6}}\)
3
\(\frac{1e^{-0.3}}{2 + 3e^{-0.3} + e^{-0.6}}\)
4
\(\frac{3e^{-0.3}}{2 + e^{-0.3} + e^{-0.6}}\)
