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 by AHan = 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 A What 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 of Formation (kJ/mol) Standard Heat of Element/ Compound Element/ Compound Formation (kJ/mol) H(g) 218 N(g) 473 H2(g) O2 (g) NH3 (g) -45.90 O(g) 249 H2O(g) HCN(g) CO(g) -110.5 -241.8kJ C(g) 71 130.5kJ C(s) HNO3 (aq) -206.6 Express the standard enthalpy of reaction to three significant figures and include the appropriate units.

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. The standard enthalpy of reaction is the enthalpy change that occurs in a reaction when 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 (AHº) (subscript "f" for formation) of its reactants and products. Therefore, the standard enthalpy AH of any reaction can be mathematically determined, as long as the standard heats of formation (AH;)of its reactants and products are known. the reactants and products
