Physical Chemistry — Practice Set 2

The first law of thermodynamics: internal energy, heat and work (including expansion work, reversible and irreversible), state versus path functions, enthalpy and the relation between ΔU and ΔH, heat capacities at constant volume and pressure, calorimetry, standard enthalpies of formation, reaction, combustion and their combination through Hess's law, bond enthalpies, and the temperature dependence of reaction enthalpy (Kirchhoff's law). Equations are shown in inline notation.
