Temkin equation
WebTemkin suggested an algorithm on the basis of eqn. (30) to obtain an explicit form of the steady-state kinetic equations. For linear mechanisms in this algorithm it is essential to apply a complex reaction graph. In some cases the derivation of a steady-state equation for non- linear mechanisms on the basis of eqn. (30) is also less difficult. WebTemkin's linear form is given in Equation (5), where R is the common gas constant (0.008314 kJ mol −1 K), T is the absolute temperature (K), 1/bT is the Temkin constant …
