What is in Unit 6: Thermochemistry?
Unit 6: Thermochemistry
6.1 Endothermic and Exothermic Processes
6.2 Energy Diagrams
- I can describe a physical or chemical process using an energy diagram that shows whether it is endothermic or exothermic.
6.3 Heat Transfer and Thermal Equilibrium
6.4 Heat Capacity and Calorimetry
6.5 Energy of Phase Changes
- I can state that energy must be transferred to a system to melt or boil, and is released when freezing or condensing, while the temperature of a pure substance remains constant.
- I can use the molar enthalpy of a phase change to calculate energy absorbed or released, and recognize that complementary phase changes have equal but opposite energy changes.
6.6 Introduction to Enthalpy of Reaction
6.7 Bond Enthalpies
6.8 Enthalpy of Formation
6.9 Hess’s Law
