The diagram shows the course of the reaction for a chemical reaction. With and without catalyst. R stands for reactant and p stands for product. Which statement or statements are true? 1. H4 and H5 together make up the total enthalpy change of the reaction.❌?
2. The reaction is endothermic.❌
3. The presence of catalyst allows a larger amount to be formed a larger amount of the products.❌?
4. H1 <0 ✅
(EXOTERM h1 <0
(Endotherm h1> 0)
5. The activation energy is higher for the catalyzed reaction ❌?
6. The reaction is exothermic
7. H1 is the total enthalpy change ✅?
Activation energy non-catalyzed reaction = H3? ✅
