Figure states energy differences for the combustion of hydrogen, an exothermic chemical reaction. The combination of oxygen gas and nitrogen gas to form nitrogen monoxide is an example of an endothermic reaction:
Draw an energy diagram for this reaction.
Answer:
Note that in an endothermic reaction, the energy of the products is bigger than the energy of the reactants. The opposite was true for an exothermic reaction.
'Cohesive energy' : In a chemical bond, it is the energy needed to dissociate a solid into isolated atoms or molecules as appropriate.
