At standard state conditions we can use tabulated heats of formation to calculate the change in enthalpy for any reaction. At temperatures other than standard conditions we use the temperature dependence of the enthalpy to derive an expression for the change in enthalpy of a reaction at any temperature in relation to a reference temperature.

This allows us to consider entropy from the perspective of the probabilities of different configurations of the constituent interacting particles in an ensemble. This conception of entropy led to the development of modern statistical thermodynamics. For systems that can exchange thermal energy with the surroundings, the equilibrium probability distribution will be the Boltzmann distribution.

In this chapter, we analyze two types of energy: heat and work. This leads to a presentation of the first law of thermodynamics that deals with the conservation of energy, stating that any changes in the total internal energy of the system must be due to exchanges of either heat or work with the surroundings.

This chapter introduces some of the concepts relating to properties of a system and the surroundings that we will need to study classical thermodynamics. In this chapter we will focus on how the macroscopic properties of a system are related to and depend on the properties of the constituent atoms and molecules.

It differentiates between fluorescence, which is quick, and phosphorescence, which is slower due to spin flips. The Jablonski diagram illustrates these processes, showing energy transitions within molecules.

In the case of mixtures, the number of moles of the different components can change as a result of a chemical reaction or a phase transition. The partial molar Gibbs energy or chemical potential can be used to determine the spontaneity of a chemical reaction or of a phase transition. We first derive an expression for the chemical potential of gases, volatile liquids, and ideal solutions.

Newton's second law is formulated for forces between particles and a harmonic oscillator system, like a mass and spring. Concepts of potential energy, restoring forces, and phase space in relation to differential equations are introduced.
