9 How is a thermochemical equation different from other chemical equations 10 Label the following two graphs from pages 536 and 537 Exothermic Reaction Enthalpy Energy as heat is evolved Din Final enthalpy Course of reaction Initial enthalpy AH AH is negative Enthalpy Endothermic Reaction Final enthalpy Energy as heat is absorbed Course of reaction 11 In an endothermic reaction is heat released or absorbed 12 In an exothermic reaction is the change in enthalpy AH positive or negative 13 Which has higher energy in an endothermic reaction the reactants or the products 14 Does the following equation represent an exothermic or an endothermic reaction 2H g O2 g 2H O g AH 483 6 kJ AH is positive AH Initial enthalpy 15 True or false When using thermochemical equations the physical state of the product or reactant involved in the reaction is not an important factor and therefore does not need to be included
