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!
40m-10m delta loop antenna - gu3whn The variety of one wave length loop shapes that can be deployed to suit the QTH . Note:- Loops A -E have sides approximately (~) 1/3 wavelength but overall circumference delta loop is the same as an equivalent quad on the same frequency, i.e. 1005 /F(MHz) feet or 306.31 /F(MHz) metres.
