  • Thermochemistry Practice Problems

    This course explores how the First Law of Thermodynamics (ΔU = Q + W) governs energy changes in chemical reactions. You will learn to quantify heat transfer (Q), work (W), and internal energy (ΔU) in reactions, with applications to calorimetry, bond energies, and reaction spontaneity. Key topics include enthalpy (H), Hess’s Law, and standard reaction heats, bridging theory with lab techniques like bomb calorimetry.
