Since I know the pka do I just find the Ka and use that to solve? Or since its for C3H602 I have to find the reciprocal of the KA value?

Re: Finding Wavlength
I don't think you could use those for the same objective. The photoelectric effect is used for finding energy of light, which does not have a rest mass. The de Broglie's, however, is used for electrons and other particles with a rest mass. Therefore, I don't think you would get the same answer, nor...

Finding Wavlength
Could you find the wavelength of an object using the photoelectric effect and De Broglie Equation and it will give you the same thing?

Will the empirical equation that Dr. Lavelle used in the lecture on Friday be able to solve the same problems that the Rydberg equation can?
