(a)
Interpretation:
Comparison of ratio of atoms or ions in 3p states and in ground state of Na atom and Mg+ is to be done when there is a natural gas air flame of temperature 1800 K.
Concept introduction:
Boltzmann equation is used for the calculation of the ratio. This equation tells that how much an atom or ion is populated as a function of temperature. This equation is given as-
And the calculation of energy of atom and ion is done by the following formula-
Where,
h= Planck’s constant
c = light velocity
λ= wavelength
Ej= energy difference of excited state and ground state

- Quantum mechanics. Explain the basis of approximating the summation to an integral in translational motion.arrow_forwardQuantum mechanics. In translational motion, the summation is replaced by an integral when evaluating the partition function. This is correct becausea) the spacing of the translational energy levels is very small compared to the product kTb) the spacing of the translational energy levels is comparable to the product kTc) the spacing of the translational energy levels is very large compared to the product kTarrow_forwardDon't used Ai solutionarrow_forward
