I Review | 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. In a generic chemical reaction involving reactants A and B and products C and D, aA + 6B→¢C+dD, the standard enthalpy AHm of the reaction is given by 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 AHm, where the subscript "rxn" stands for "reaction." The standard enthalpy of a reaction is calculated from the standard heats of formation (AH?) ΔΗΡcΔΗ (C) + dΔΗ; (D) -αΔΗ (Α) - bΔΗ; (Β) 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:…
