Gibbs Free Energy in Reaction Profiles

Postby Diondraya_Taylor_1C » Wed Mar 08, 2017 7:54 pm

I'm a little confused as to what Gibbs free energy means in terms of the reaction process/reaction profiles. Could someone clarify/explain? Thanks!

As seen in the picture, ΔG refers to the difference in energy between the reactants and products. ΔG controls the thermodynamics of the reaction, or whether the reaction is spontaneous or non-spontaneous.

ΔG‡ refers to the difference in energy between the reactants and the transition state. ΔG‡ controls the kinetics of the reaction, the speed or rate of the reaction.

In drawing out the transition state (as shown above), are there points associated with writing out the partial charges of the atoms with the partially formed/broken bonds? In other words, will points be deducted if the transition state structure is drawn correctly, but does not include the partial charges?
