You probably know that a correlation is the relationship between two sets of variables used to describe or predict information. Therefore, the correlation coefficient is the degree in which the change in a set of variables is related.
Delta G is a measure of the net effect of these two concepts, and will help you predict whether or not a reaction will actually take place! Delta G naught refers to the Delta G if you were creating a given compound from its pure elemental form at standard temperature and pressure. So it's how likely a compound would form from its individual elemental components!
Report Abuse. Delta G is the work exchanged by the system and the surroundings. It is just a matter of definition. (Delta H) - T(delta S) implies the energy given by the surroundings to the system, therefore when it is negative it means the system gave energy to the surroundings, and therefore it was a spontaneous process. If it had been defined as T(delta S) - (Delta H) it would have been the opposite.
