Gibbs-Helmholz equation

K is therefore a function of temperature through the term RT, where R is the gas constant, 8.314 J mol K and Tis the temperature expressed in Kelvin (K). The value of the constant given in Equation 6.13 depends on how the abundance of the solute or chemical is expressed i.e. partial pressure, mole fraction or molar concentration. For mole fraction the constant has a value of 1, whereby In 1 = 0 and can therefore be ignored. Rearranging Equation 6.13 to solve for AG , and then combining with the Gibbs-Helmholz equation results in... [Pg.293]

It is possible to change the extent to which a reaction proceeds by changing the temperature. Since AG T = —Rln K, the temperature dependence of the equilibrium constant follows directly from the Gibbs-Helmholz equation (12)... [Pg.180]
