Gibbs LS7A

Postby Helen Struble 2F » Sun Feb 09, 2020 9:15 pm

In LS7A, two equations are given for Gibbs free energy:

1) deltaG = deltaH - TdeltaS
2) deltaG = G(standard) + RTlnQ

Can someone relate these two equations? If deltaG is a state function (does not change with path), why would the concentrations of products and reactants affect deltaG?

For your second question: Changing the concentrations of products and reactants would change Q which is apart of the second equation

We aren't required to know the second equation for the midterm; this is covered in chapter 5, which Lavelle hasn't gone over yet
