Statistical Thermodynamics provides the link between the microscopic properties of matter and its bulk (macroscopic) properties. It answers one of the most important question in Chemistry: how are the molecules distributed over the energy states at a given temperature? Two major concepts: The Boltzmann Factor and the Partition Function

The system is defined as an ensemble or macroscopic systems in thermal equilibrium with a heat reservoir. The number of the system in a state j with an energy associated E j (N,V) is a j and the total number of the systems is A . E1 E2 E3 E1 E2 E3 E1 E2 E3 E1 E2 E3

The simplest case we consider is a monoatomic gas with only translational energy. For this system, we can define the total energy, E j (N,V), simply by adding the energy of each individual molecular energies: N j V N E ε ε ε ε + + + + = .... ) , ( 3 2 1 Where N is the total number of molecules and ε j the individual energies of the molecules
