Key Concepts

Equilibrium Constant (K)

The equilibrium constant (K) quantifies the ratio of concentrations of products to reactants at equilibrium for a given reaction. It is related to the Gibbs free energy change through the equation ?G° = –RT lnK, where R is the gas constant and T is the temperature in Kelvin. This connection allows chemists to predict the position of equilibrium based on the cell potential and Gibbs free energy.

Standard Electrode Potentials

Standard electrode potentials are measures of the tendency of a chemical species to be reduced, relative to the standard hydrogen electrode. They enable the calculation of the overall cell potential when multiple half?reactions are involved. Understanding how to combine and reverse half?reactions is essential for determining the net cell reaction potential.

Gibbs Free Energy Change (?G°)

Gibbs free energy change (?G°) is a thermodynamic quantity that indicates the spontaneity of a reaction under standard conditions. It is directly related to the cell potential via the equation ?G° = –nFE°, where n represents the number of electrons transferred and F is Faraday’s constant. This relationship bridges electrochemistry and thermodynamics, showing how electrical work is converted into chemical energy.
