Answer:
The difference between the energy of the reactants and the energy of the products is called the enthalpy change (âH) of the reaction. For an exothermic reaction, the enthalpy change is always negative. In an endothermic reaction, the products are at a higher energy than the reactants.
Explanation:
Answer:
1. Â lower energy of reactants
2. Â higher energy of products
3. Â Â transition state
