Relating Hess’s Law to Energy Cycles
This post will follow on last post and go into the analysing relationships between Hess’s Law and energy cycles for Prelim Chemistry.
Topic: Enthalpy and Hess’s Law
- Apply Hess’s Law to simple energy cycles and solve problems to quantify enthalpy changes within reactions, including but not limited to:
- Heat of combustion
- Enthalpy changes involved in photosynthesis
- Enthalpy changes involved in respiration
What are Energy Cycles?
The energy cycle can be thought of as the steps a reaction takes to get to the product, the reaction pathway. This video below will introduce you to drawing simple energy cycles.
Heat of Combustion, Photosynthesis and Respiration
This video goes through an energy cycle of combustion.
This video goes relates Hess’s Law to Photosynthesis.
