The reaction is endothermic and the products have a higher AH than the reactants

Explanation:

In an endothermic reaction, heat is absorbed from the surroundings and the surrounding becomes colder at the end of the changes. Here ΔH is assigned a positive sign as the heat energy level of the final state(products) is higher than that of the initial state(reactants).

We see from the curve that the products are at a much higher enthalpy compared with the reactants.

chemists can use the electron cloud model to assign electrons to different atomic orbitals. atomic orbitals also explain the patterns in the periodic table
