The derived ways of empiric-order autocatalytic reaction rate equation and its thirteen derived formulae were presented The equation of rate curve characteristics [α_max and (dα/dt)_max] and the equation of change in reaction extent (α) with time (t) and temperature (T) describing the autocatalytic reaction were derived. The computer program of calculating the kinetic parameters (E, A or E₁, A₁, E₂, A₂) and empiric-order (m, n, p) of autocatalytic reaction and the values of α_max and (dα/dt)_max was written. The rate equation describing the autocatalytic decomposition reaction of hexanitrohexaazaisowurtzitane (HNIW) and the kinetic parameters, catalytic coefficient K_cat, rate curve characteristic parameters and the equation of change in α with t describing the autocatalytic decomposition reaction of nitrocellulose (NC) (12.82%, 12.97%, 13.54%, 13.61%, 13.88%, 14.14% N) were presented.
