Answer my question. #6-10: consider the energy diagram below: 6. what is the activation energy for this reaction? 7. what is the change in free energy for the reaction? 8. how many intermediates are involved in this reaction? 9. how many transition states are involved in the reaction mechanism? 10. is the reaction endergonic or exergonic overall?

6. Activation energy is the difference in energy between the reactant and the transition state. The energy of the reactant and the transition state are 5 kJ/mol and 15 kJ/mol respectively. The activation energy for this reaction is 10 kJ/mol.

7. The change in free energy for the reaction is the difference in energy between the reactant and the product. The energy of the reactant and the product are 5 kJ/mol and 10 kJ/mol respectively. The change in free energy for the reaction is 5 kJ/mol.

8. There are no intermediates involved in this reaction.

9.  There is only one transition state involved in the reaction mechanism. The transition state is indicated by the highest point of the graph.

10. The reaction is endergonic overall. The energy of the product is higher than the energy of the reactants, which is only possible if energy is absorbed by the reaction.

alchemy hadn't scientific methods of study, appeal to mysticism and fantasy, the knowledge of chemistry and physics were modest at that time.

alchemy was - but as new rules were discovered it either changed into chemistry or it became "unscientific".
