Unit 11 BIOMG 3300 questions with complete solutions.

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 ...
