Respuesta :
The conditions that must be true for all products is that the change in enthalpy is positive and the potential energy diagram is lower.
An endothermic chemical reaction is one that gains energy from the environment; therefore the energy of the products is higher than that of the reactants.

Answer: Option (a) is the correct answer.
Explanation:
A chemical reaction in which energy or heat is absorbed by the reactant molecules is known as endothermic reaction.
Since heat is being absorbed so products formed will have high energy. Hence, change in enthalpy will be positive.
Thus, we can conclude that the change in enthalpy is positive and potential energy diagram is higher.
