Hess's Law
Students will apply Hess's Law to calculate enthalpy changes for reactions that cannot be measured directly.
Key Questions
- Explain how Hess's Law is a direct consequence of enthalpy being a state function.
- Construct a reaction pathway to calculate the overall enthalpy change using Hess's Law.
- Justify the use of Hess's Law in determining the enthalpy of formation for complex compounds.
