In a generic chemical reaction involving reactants A and B and products C and D, aA + 6B+cC + dD, the standard enthalpy AHn of the reaction is given by AH = cAH; (C) + dAH; (D) –aAH (A) - bAH (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: AHn = Eproducts nAH - Ectants mAH %3D where m and n represent the appropriate stoichiometric coefficients for each substance.

![Standard Enthalpy of Reaction

Learning Goal:
To understand how standard enthalpy of reaction is
related to the standard heats of formation of the
reactants and products.
Constants Periodic Table
In a generic chemical reaction involving reactants A and B and products C and D, aA + bB-cC + dD, the
standard enthalpy AHn 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
AHn, where the subscript "rxn" stands for
"reaction." The standard enthalpy of a reaction is
calculated from the standard heats of formation (
AH) (subscript "f" for formation) of its reactants
and products. Therefore, the standard enthalpy
AHn of any reaction can be mathematically
determined, as long as the standard heats of
formation (AH:) of its reactants and products are
AH = cAH¿ (C) + dAH; (D) -aAH; (A) – bAH (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:
AHn =Eoroducts nAH – Eactants mAH
where m and n represent the appropriate stoichiometric coefficients for each substance.
