What is the most important thing change in Gibbs free energy tells us? What does a negative 
value mean and what does a positive value mean? - how spontaneous a reaction is 
negative delta G = spontaneous, energy is released, exergonic 
positive delta G = non-spontaneous, energy is consumed, endergonic 
what does enthalpy represent? what does it mean when it's positive vs negative? - delta 
H is change in enthalpy, which is the heat content of the reacting system. 
It reflects the number and ...
