which describes the enthalpy change associated with an endothermic reaction?

Enthalpy change is a term used in thermodynamics to describe the amount of heat energy absorbed or released during a chemical reaction. In an endothermic reaction, energy is absorbed from the surroundings, resulting in an increase in enthalpy. This increase in enthalpy is referred to as a positive enthalpy change, as the system gains energy.

The enthalpy change associated with an endothermic reaction can be calculated using the equation ΔH = H(products) - H(reactants). The enthalpy of the reactants is subtracted from the enthalpy of the products to determine the change in enthalpy. Since the products have a higher enthalpy than the reactants, the enthalpy change is positive.

It is important to note that the enthalpy change is a measure of the heat energy exchanged between the system and the surroundings, not the temperature change of the system. Therefore, an endothermic reaction can occur at constant temperature, as the absorbed energy is used to break bonds and initiate the reaction rather than increasing the temperature.

Overall, the enthalpy change associated with an endothermic reaction is a positive value that represents the energy absorbed from the surroundings during the reaction.
