Receptor and Ligand Equilibria

A large number of biological reactions involve binding of one molecule to another. One of them is usually small and we call it a ligand, L. The other is usually large and 

There are new and perhaps unfamiliar words in the riddle given above. You will do well to learn how to ignore them and look for the essence of the question here. And the essence is the binding of a ligand to a receptor to give a receptor-ligand complex. Translated into symbols these English words look like 

Given are AH and AS and the temperature find the JCeq for this reaction . In your textbook, under the chapter Second Law of Thermodynamics you will find the most important thermodynamic equation  

In the chapter titled Chemical Equilibrium you will find what 1 think is the most important physical chemistry equation  

Good - now what to do with these equations You need to know K q. You will calculate it from the AG in (7-10). First, you will insert the numbers given for the
