Which describes the enthalpy change associated with an endothermic reaction?
It is negative because the enthalpy of the products is greater than the enthalpy of the reactants.
It is positive because the enthalpy of the products is greater than the enthalpy of the reactants.
It is negative because the enthalpy of the reactants is greater than the enthalpy of the products.
It is positive because the enthalpy of the reactants is greater than the enthalpy of the products.

Answer 1

The answer would be:
B. It is positive because the enthalpy of the products is greater than the enthalpy of the reactants.

The endothermic reaction has a positive enthalpy change because it absorbs the energy of the system. Since the product of the reaction has a greater enthalpy than the reactant, the reaction needs to take the extra energy from the system. Since the system losing energy, the surrounding temperature will drop.

Answer 2

The answer is option B)
