Yes, it is a correct approach because endothermic reactions absorb heat. In consequence, the amount of heat can be used to classify this reaction.
<h3>Endothermic and exothermic reactions</h3>
An exothermic reaction is a type of chemical reaction that releases heat, thereby increasing the temperature of its surrounding environment.
Conversely, an endothermic reaction can absorb heat, thereby cooling its surrounding environment.
In consequence, the amount of heat measured after the reaction can be indicative of the type of chemical reaction.
