Thermochemistry connects to later units in AP Chemistry. Solid practice now reduces rework when those ideas reappear in combined scenarios.
Energy changes in chemical processes, enthalpy, calorimetry, and heat transfer. Expect questions involving Endothermic vs exothermic processes, enthalpy changes; Calorimetry and heat capacity calculations; Hess’s Law and enthalpy of formation.
After each practice question, write one sentence explaining why the correct answer works. That habit transfers directly to AP Chemistry free response reasoning.
