In a generic chemical reaction involving reactants A and B and products C and D, aA + bB>cC+dD, the standard enthalpy AHen of the reaction is given byAHan = 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 - Ereactants mAH;where m and n represent the appropriate stoichiometric coefficients for each substance.Part AWhat is AHm for the following chemical reaction?CO(g) + NH3(g)→HCN(g)+H2O(g)You can use the following table of standard heats of formation (AH) to calculate the enthalpy of the given reaction.Standard Heat ofFormation (kJ/mol)Standard Heat ofElement/ CompoundElement/ CompoundFormation (kJ/mol)H(g)218N(g)473H2(g)O2 (g)NH3 (g)-45.90O(g)249H2O(g)HCN(g)CO(g)-110.5-241.8kJC(g)71130.5kJC(s)HNO3 (aq)-206.6Express the standard enthalpy of reaction to three significant figures and include the appropriate units. Standard Enthalpy of ReactionLearning Goal:To understand how standard enthalpy of reaction is relatedto the standard heats of formation of the reactants andproducts.The standard enthalpy of reaction is the enthalpy changethat occurs in a reaction whenare in their standard states. The symbol for the standardenthalpy of reaction is AHn, where the subscript "rxn"stands for "reaction." The standard enthalpy of a reaction iscalculated from the standard heats of formation (AHº)(subscript "f" for formation) of its reactants and products.Therefore, the standard enthalpy AH of any reaction canbe mathematically determined, as long as the standard heatsof formation (AH;)of its reactants and products are known.the reactants and products
