Answer:
In an endothermic reaction, the products are higher in energy than the reactants. Therefore, the change in enthalpy is positive, and heat is absorbed from the surroundings by the reaction.
Heat is added to the reaction equation at the reactant side.
An endothermic reaction is a reaction in which the heat supplied is a reactant. This means that heat is added to the reaction equation at the reactant side.
