Which of the following is a statement of hess's law? if a reaction is carried out in a series of steps, the δh for the reaction will equal the sum of the enthalpy changes for the individual steps. the δh of a reaction depends on the physical states of the reactants and products. the δh for a process in the forward direction is equal in magnitude and opposite in sign to the δh for the process in the reverse direction. the δh for a process in the forward direction is equal to the δh for the process in the reverse direction. if a reaction is carried out in a series of steps, the δh for the reaction will equal the product of the enthalpy changes for the individual steps.

A) If a reaction is carried out in a series of steps, the ΔH for the reaction will equal the sum of the enthalpy changes for the individual steps. ... C) The ΔH for a process in the forward direction is equal in magnitude and opposite in sign to ... E) The ΔH of a reaction depends on the physical states of the reactants and products.

Explanation:

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
