Abstract: Gibbs energy, G [J], is an extensive quantity, defined relative to a reference state of a system, comparable to altitude [m] defined relative to a reference (altitude at sea level). When a chemical reaction proceeds in a closed isothermal system, the Gibbs energy of the system undergoes a change, drG, [J]. Force is an intensive quantity. An isomorphic force is defined as the partial derivative of Gibbs energy (exergy) per advancement of a transformation, ฮtrF = dtrG/dtrฮพ. The driving force of a reaction (compare affinity), therefore, is ฮrF = drG/drฮพ [Jยทmol-1].
