How do you tell the difference between an endothermic reaction and an exothermic reaction?
Are you referring to the equations of these reactions? If so, read on...
When we write the equation of an exothermic reaction, we either include the energy released on the product side of the equation, or better still, we write
In an endothermic reaction, the energy term can be written as part of the reactants, or using the same
In a practical sense, telling these apart is easy, as the exothermic reaction will generate heat (although sometimes in small amounts, or too slowly to be easily noticeable). An endothermic reaction will generally be accompanied by a cooling of the reaction vessel.
