Preliminary Results on the Nature of n in Equation (dx/dt)=(a-x)n as Applied to Three Solid Thermal Decomposition Reactions

  • D. M. Speros
  • H. R. Werner


The relation
$$ \frac{{d\alpha }}{{dt}} = k{(1 - \alpha )^n} $$
a fundamental equation in homogeneous kinetics, has been widely applied to solid-state chemistry. This application has been as widely contested because the physical significance of the equation in solid reactivity has not been elucidated. This is particularly true for values of n other than 0, 1/2, 2/3. and 1 , yet precise experimental results show that n frequently acquires values other than these. Thus, the equation has been used mainly for purposes of analytical convenience.
