Trend Lab
Question about free energy?

We had a chemistry lab and determine the Gibbs free energy of a titration done at different temperatures. When I graph free energy vs temperature, the trend has been positive. The draft report Laboratory told me why my tendency is positive, but I do not know why this happens. Anyone know?

DG = DH – TDS So, if your reaction has a positive DS, then DG will become more negative at higher temperatures. If your reaction has a negative DS, then DG will become more positive at higher temperatures. Why you would see in a titration it is not immediately obvious to me.
