How do I comment on the Gibbs energy values standard and reaction in different situations? I have the following graphs:


Taking into account the following graphs, how do I comment on the Gibbs energy values
standard and Gibbs energy of reaction in different situations (a, b and c), and how do I relate the values of the latter to the spontaneity of the reaction? I'm really lost here.
Here is a labeled and annotated version of your graph (from OpenStax Chemistry).
