Nernst Equation
Nernst Equation
The Nernst equation relates the Gibbs free energy change for a reaction to the cell potential, temperature, and the standard cell potential.
Schrödinger Equation
Schrödinger Equation
The Schrödinger equation describes the behavior of an electron in an atom or a molecule. The time-independent form describes the stationary state of the electron where energy is constant, while the time-dependent form describes the evolution of the electron's wave function over time.
Van der Waals Forces
Van der Waals Forces
Van der Waals forces are weak intermolecular forces that arise from temporary fluctuations in electron distribution. These forces are responsible for the deviation of real gases from ideal gas behavior.
