Questions & Step-by-Step Solutions

Which law states that the total enthalpy change in a reaction is the same regardless of the number of steps in the reaction?
  • Step 1: Understand what enthalpy change means. It is the heat content change during a chemical reaction.
  • Step 2: Learn about Hess's Law. It says that the total enthalpy change for a reaction is the same no matter how many steps the reaction takes.
  • Step 3: Realize that this means if a reaction can happen in one step or several steps, the total energy change will be the same.
  • Step 4: Remember that Hess's Law helps us calculate the enthalpy change for complex reactions by breaking them down into simpler steps.
