In the reaction there is a heat loss, and is therefore an ............. reaction. (10) 4. This is the standard enthalpy change that takes place when 1 mole of a substance reacts completely with oxygen. (10) Down 2. This is the enthalpy change that takes place when 1 mole of a compound is formed from its constituent elements. (9) 3. This is the law that states if a reaction acn take place by more than 1 route, then the enthalpy change for each route would be the same. (4) 5. This is the enthalpy change that takes place by homolytic fission. (4) 6. This is a type of energy that that acts as a barrier that prevents reactions from taking place spontaneously. (10)
