Characteristics

Characteristics

Characteristics. Voltammetry is based upon the measurement of a current that develops in an electrochemical cell under conditions of complete concentration polarization. Potentiometric measurements are made at currents that approach zero and where polarization is absent

Review of Thermodynamics

Review of Thermodynamics

Review of Thermodynamics. 1 ? Free Energy( ??? ) ? When one is concerned with changes in the state of a system, a full description requires knowledge of what is known as the free energy, including the Helmholtz free energy and the Gibbs free energy.

The Thermodynamic Potentials

The Thermodynamic Potentials

The Thermodynamic Potentials. Four Fundamental Thermodynamic Potentials. Equilibrium. dU = TdS - pdV dH = TdS + Vdp dG = Vdp - SdT d A = -pdV - SdT. fixed V,S. fixed S,P. fixed P,T. fixed T,V. The appropriate thermodynamic potential to use is determined by the constraints
