Question

How will you judge whether a chemical reaction is exothermic or endothermic in nature?

Answer 1

In a chemical reaction if heat is given out then it is exothermic reaction and if heat is required for the chemical reaction to take place then it is a endothermic reaction

Answer 2

Explanation:

In a chemical equation, the location of the word "heat" can be used to quickly determine whether the reaction is endothermic or exothermic. If heat is released as a product of the reaction, the reaction is exothermic. If heat is listed on the side of the reactants, the reaction is endothermic.
