I'm working on a physical chemistry project that is a report on a paper that uses X-ray crystallography to characterize a protein. So I am studying X-ray crystallography more in depth than the book introduces, and I have a few questions that I couldn't really find answers to online. 1. How...

Homework Statement Consider a container with two chambers of the same size separated by a fixed membrane in the middle (permeable only to the ideal solute, but not the solvent). One chamber initially contains 1M of solute, and the other contains 0.5M of solute. Write an equation for the...

Here's a radioactive binding assay: 1. Mix radioactively labeled ligand of known concentration with normal ligand (assuming radioactivity does not affect the ability to bind). 2. Add the mixture of labeled and unlabeled ligand into the solution of receptor. 3. Separate bound ligand from...

Thanks for clarifying some of my confusions! But for ΔS= q/T, I thought it was defined as dS=dq(rev.)/T, so you would have to integrate the function to get the entropy change. If T is not constant, why can you take it out of the integral and simply integrate dq to get q? Thanks again!

Homework Statement A system with 100,000 molecules has 2 energy levels, A and B. At first, the 2 energy levels are populated equally. After a reversible process, energy level A is populated by 65% of the molecules and the system is at 293K. a) What is the difference in energy between the two...
