One way to measure ionization energies is ultraviolet photoelectron spectroscopy (UPS, or just PES), a technique based on the photoelectric effect. In PES, monochromatic light is directed onto a sample, causing electrons to be emitted. The kinetic energy of the emitted electrons is measured. The difference between the energy of the photons and the kinetic energy of the electrons corresponds to the energy needed to remove the electrons (that is, the ionization energy). Suppose that a PES experiment is performed in which mercury vapor is irradiated with ultraviolet light of wavelength 91.5 nm. (a) What is the energy of a photon of this light in eV (1 eV = 1.602e-19J)?

What is the dissociation constant, Kd, of a ligand with a percent occupancy (or fractional saturation) of 50% when [ligand] = 10-7 M
Which reagent is used in excess? How great is the molar excess (how many times greater)? I'll add the procedure images in the comments
If a molecule is more affected by London Dispersion forces that means it will have a higher melting point. if big molecules are less affected by dipole-dipole attractions, they will have a higher melting point. are these statements true?
