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. WebTnxKiN and PYZHEY [1] and EMMETT and K>OxEIt [4] have applied the kinetic equation to experimental data at pressures up to 100 atm for various space velocities, H2/N2 ratios and degrees of approach to equilibrium. The data were …
