a. Does ∆H°reaction or ∆H is calculated according to the coefficient right before each molecule, then times the thermodynamic energy each molecule owns?
b. Whereas for ∆H°formation, the coefficient of the product must be converted to 1 mol, and the coefficient of reactants must be converted accordingly, then times the thermodynamic energy each molecule owns? Thanks!

Constants | Periodic Table Learning Goal: To understand how standard enthalpy of reaction is related to the standard heats of formation of the reactants and products. The standard enthalpy of reaction is the enthalpy change that occurs in a reaction when all the reactants and products are in their standard states. The symbol for the standard enthalpy of reaction is ΔH∘rxn, where the subscript "rxn" stands for "reaction." The standard enthalpy of a reaction is calculated from the standard heats...

In a generic chemical reaction involving reactants A and B and products C and D, aA+bB→cC+dD, the standard enthalpy ΔrH∘ of the reaction is given by ΔrH∘=cΔfH∘(C)+dΔfH∘(D) −aΔfH∘(A)−bΔfH∘(B) Notice that the stoichiometric coefficients, a, b, c, d, are an important part of this equation. This formula is often generalized as follows, where the first sum on the right-hand side of the equation is a sum over the products and the second sum is over the reactants: ΔrH∘=∑productsnΔfH∘−∑reactantsmΔfH∘ where m and...

Chemical Reactions Types and Their Equations Making Heat with Chemical Reactions Have you ever wondered how an instant heat pack works? A disposable heat pack works by a chemical reaction that combines iron in the package with oxygen from the air when the outer packaging is removed producing iron oxide. You have probably seen the product of this reaction in what is commonly called rust. The reaction releases heat, which allows the pack to reach a sufficient temperature that is...
