The standard enthalpy of a reaction, AH, is the energy or enthalpy change associated with transforming reactants into products, where "standard", denoted °, implies reaction conditions of 25°C, 1 atm and/or 1 M. Standard enthalpies of a reaction can be estimated by assuming that all reactant bonds are broken before forming all product bonds: AHTD =( enthalpies of bonds broken) - (2 enthalpies of bonds formed) Using the information below, calculate AH°r (kJ) for the reaction of H2(g) + Cl2(g)...

the enthalpy change in a chemical reaction can be determined using bond energies. energy must be added or absorbed to break bonds and that energy is released when bonds are formed. therefore ,you can calculate the total enthalpy of the reaction using following formula: dH= bonds broken-bonds formed Using bond energies, calculate the change in energy that accompanies the following reaction: H2 + O2 -> 2H2O Bond Bond Energy H-H 432 kJ/mol O-O 498 kJ/mol H-O 467 kJ/mol
