While it is a very important point for the lay person to know that the acidification of the ocean by CO2 (it combines with water to produce dilute Carbonic Acid) can reduce the effectiveness of the Calcium Carbonate processes at sequestering Carbon (and can even reverse it, by dissolving Calcium Carbonate), your model chemistry seems quite simplistic.

Physical chemistry is a combination of chemistry and physics, it is fine that you derived the equation, but it relates to thermodynamics just the same; chemists make those lasers work, those DVD's play, and I have taken calculus physics, modern physics, (multi variable calculus physics) which means technically I too have a degree in physics, but my focus has been chemistry, biology, and I took a few graduate courses dealing with meteorology, ocean dynamics, geology, atmospheric science and my undergraduate courses were filled with earth science related material and after all the math needed for Pchem engineering mathematics is not difficult nor is graduate physics:) so the derivation you just made is discussed in math classes before, even calculus one, so I am not sure what you are trying to prove.
