Chemical Energy & Thermodynamics — Chapter overview · Physical Science: Chemistry, Grade 11
Use calorimetry, Hess’s law, entropy, and free energy with explicit systems and signs.
Chapter question
Where does reaction energy go, and what favors change?
Units in this chapter
- Unit 9.1 · Energy in Chemical Reactions
I can classify a reaction as endothermic or exothermic from its energy flow, temperature change, and the sign of ΔH.
- Unit 9.2 · Calorimetry, Hess’s Law & Enthalpy Calculations
I can determine reaction heat from a measured surroundings change with consistent signs.
- Unit 9.3 · Entropy, Free Energy & Reaction Feasibility
I can calculate ΔG with consistent energy units and kelvin temperature.
