1. An atom of mass 2.66 ? 10-26 kg oscillates in one dimension at a frequency of 0.60 ? 1013 Hz. What is its effective force constant?
What are its quantized energy levels?
2. A H2 molecule can be approximated by a simple harmonic oscillator having a spring constant k = 1.1 ? 103 N/m.
(a) How many different energy transitions are possible when the H2 molecule decays from the third excited state down to the ground state?
(b) Find the photon energies produced in these transitions and their wavelengths.
3. Let 10.0 eV electrons approach a potential barrier of height 4.4 eV.

find the work done to move the particle from x = 0 to x = 10.0 m by graphically determining the area under the F versus x graph. (Do this on paper. Your instructor may ask you to turn in this graph.)
What are the frequencies of vibration for the normal modes of this system? What are eigenvectors?
A 6-m3 rigid tank initially contains a mixture of 1 kmol of hydrogen (H2) gas and the stoichiometric amount of air at 25°C. The contents of the tank are ignited, and all the hydrogen in the fuel burns to H2O. If the combustion products are cooled ..
