Heat of reaction and enthalpy of reaction are the same thing. Enthalpy, or the heat transfer, cannot be measured, however we can measure the CHANGE of enthalpy which is shown by a value of ∆H. This measured in kilojoules per mole of reactant. (KJ/mol)
This value may be positive or negative. For endothermic reactions (which absorb heat), the ∆H value is always positive. For exothermic, where heat is released, the value is negative.

What is the enthalpy of reaction apex's?
The heat released or absorbed in a reaction apex
What does the enthalpy of reaction measure?
The amount of energy that is used or released as heat in a reaction.
What kind of enthalpy change favors a spontaneous reaction?
An exothermic reaction is a chemical reaction that releases energy in the form of heat. It favors a negative enthalpy change.
Heat given off or absorbed in a reaction is called?
Enthalpy
What is the sign of the enthalpy change for an endothermic reaction?
Endothermic reaction: 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 therefore enthalpy change show positive sign in a endothermic reaction..
What is the description of the enthalpy of a reaction?
The enthalpy of a chemical reaction is the change of heat during this reaction.
