Enthalpy of formation is the change in enthalpy required to create one mole of the substance from its pure elements, and enthalpy of combustion is the change in enthalpy required to break down one mole of the substance into its pure elements. Read Hess's Law | Definition, Diagram & Equation...
Determine: (1) the number of degrees of molecular freedom, (2) the change of internal energy ΔU, and (3) the change of enthalpy ΔH. Solution: (1) It was mentioned that the process is rapid, therefore, it can be considered an adiabatic one. The equation for an adiabatic process (...
The family of Gibbs–Helmholtz equations connect phase and chemical equilibrium with enthalpy and volume. This family of equations is one of the most useful—yet unappreciated and poorly understood—mathematical relations in chemical thermodynamics. This paper rigorously derives several variants of the Gib...
