6 PROBLEM SET HEAT CALCULATIONS PRACTICE SC5 ab and SC2 g I am learning to determine the energy change in a chervical reaction Can I calculate the enthalpy change of a chemical reaction 0 using Hess s Law using changes in total bond energy Can I develop a model reaction diagram to illustrate the release or absorption of energy from a chemical reaction system depending upon the changes in total bond energy Using both Hess s Low with Enthalpy of Formation AH values and Bond Enthalpies find the AH for 2 NO g O g 2 NO g Hess s Law with Enthalpy of Formation AH Values Chemical Equation including Energy 14 Temp Phase Chem Kinatie E Potential E attractions Bond Enthalpy Then write the chemical equation with the energy term included Next represent the energy storage and transfer using bar graphs sketch the chemical energy curve ENERGY FLOW 2 NO g O g 2 NO g Reactants Temp Phase Chon bet Potent tattractions ENERGY FLOW is the reaction exothermic or endothermic Products Tanp Phase Chan KE Petal seftracted 2 0 0 2 N Substance NO g POTENTIAL ENERGY NO g AR Bond N O 0 0 NUO 90 TIME 0 34 Reaction Coordinate Bond Enthalpy 607 495 2017 Which is more accurate the Hess Enthalpy of Formation method or the Bond Energy method Why
