Thermodynamics Outline Second Page

Postby MariaJohn1D » Thu Feb 20, 2020 1:18 pm

For the first bullet point on the second page of the outline, what is the explanation for "why reaction free energy depends on pressure and the equilibrium constant?"

As I discussed in class:

delta G = delta Go + RT ln Q

and

delta Go = - RT ln K

For gas phase reactions Q and K depend on the partial pressure of each reactant and product.

For aqueous reactions Q and K depend on the concentration of each reactant and product.

That involves the equations G=RTlnQ and G=RTlnK.
