Hess's Law of Constant Heat Summation
Students will apply Hess's Law to calculate enthalpy changes for reactions that are difficult to measure directly.
Key Questions
- Apply Hess's Law to determine the enthalpy change for a multi-step reaction.
- Justify why Hess's Law is valid based on enthalpy being a state function.
- Construct a reaction pathway to calculate an unknown enthalpy change from known reactions.
