3. Hess' Law states...

  • if the reaction can take place by more than one route and the initial and final Hess' are the same, the total enthalpy change is the same for each route
  • if the reaction can take place by more than one route and the initial and final temperatures are the same, the total enthalpy change is the same for each route
  • if a reaction can take place by more than one route and the initial and final conditions are the same, the total enthalpy change is the same for each route
  • if the reaction can take place by more than one route and the initial and final masses are the same, the total enthalpy change is the same for each route
