Thermochemistry Exam Review | 30 Practice Problems with Solutions | General Chemistry 1

Prepare for your General Chemistry 1 thermochemistry exam with 30 fully worked practice problems and step-by-step solutions! This comprehensive thermochemistry exam review covers calorimetry, specific heat capacity, Hess's Law, enthalpy changes, bond energies, the First Law of Thermodynamics, and internal energy. Whether you're studying for a college General Chemistry 1 exam, reviewing thermochemistry calculations, or preparing for a cumulative chemistry final, this practice test will help you understand how to set up equations, convert units, and solve challenging problems. Topics covered in this thermochemistry exam review Specific heat capacity and q = mcΔT calculations Heat transfer and thermal equilibrium Coffee-cup calorimetry and bomb calorimetry The First Law of Thermodynamics, ΔE = q + w Pressure-volume work, expansion, and compression Endothermic and exothermic reactions Heating curves and phase changes Hess's Law practice problems Enthalpy changes and thermochemical equations Standard enthalpies of formation Bond energy calculations and Lewis structures Reaction energy diagrams and activation energy Heat, temperature, enthalpy, and internal energy Multi-step thermochemistry calculations How to use this practice test Pause the video before each solution and try solving the question independently. Then follow along as we identify the correct equation, organize the given information, set up dimensional analysis, cancel units, and calculate the final answer. Every problem includes a detailed explanation to help you understand the chemistry behind the calculations rather than simply memorizing formulas. This review is especially helpful for General Chemistry 1 students preparing for a thermochemistry unit exam, college chemistry midterm, or cumulative final exam.
