Calculate the ratio of HBr molecules in the first excited vibrational state compared to the ground state at 800K. Remember that finding the probability of finding a molecule in a given state, i, is related to its energy, Ei, by the following equation:
P(n) e^(-En/KT)
You will need the following information to calculate the energy of the vibrational states:
En = hv(n+1/2)
for HBr v= 7.944*10^14s^-1
K=1.3807*10^-24J/K
h=6.626*10^-34J*s
