Now, this guy is now our term used to adjust for non equilibrium and nonstandard state conditions. Now, this is still our free energy at equilibrium for state and state conditions. And this is the actual free energy at some point in our reaction. Now, let's look at this reaction. Suppose we had some reaction that wasn't at Stan and state condition and that wasn't an equilibrium. So our reactant A was an acre state, reactant B was an acre state, our product C was also an acrylic state.
