A. Suppose CO adsorbs onto a solid surface such that the CO bond is perpendicular to the surface, the oxygen atom is immobilized on the surface but the carbon atom can still move as the bond vibrates. Calculate the reduced mass for this surface-adsorbed CO molecule
B. Calculate the vibration temperature θvib for this surface-adsorbed 12C16O molecule. Assume the CO bond force constant (k= 1860 Nm^-1) does not change when CO adsorbs to teh surface.
C. Calculate the vibrational partition function for surface-adsorbed CO. Assume T=300K
D. Calculate the contribution to the molar internal energy from vibrations of the bond of surface-adsorbed CO. Assume T=300K
E. Calculate the change in the molar vibrational energy when CO adsorbs onto a surface from the gas phase. Assume T=300K

(30) Given the equilibrium bond length of CO is 1.138, explore population fractions (Eq. 2) of the ground state and first 15 pure rotational excited states relative to the ground state (where {=0). Mathematica is recommended. Do this at 298 K and at 100 K. Comment on how the results differ compared to part a). 1) In the application of quantum mechanical and statistical mechanical principles to samples containing large numbers of species (e.g. macroscopic samples of molecules), there is...

Problem 1 N molecules of carbon dioxide gas Co, (considered as an ideal gas) undergo the cycle shown in the P-V diagram on the right. As a reminder, a CO, molecule has all atoms on a line. Assume that all processes are quasistatic and that the temperature remains such that rotational degrees of freedom are activated, but vibrational degrees of freedom are frozen out. Capital letters A, B, C represent the states at the corners of the cycle, while lowercase...
