摘要: This paper studies two-step exothermic reactions with and without reactants consumption subject to Arrhenius kinetics model. The resulting system of equations modelling the physical problem is coupled nonlinear ordinary differential equations. Analytical investigations are possible based on some classical Frank- Kamenetskii criteria. Exact analytical expressions derived for temperatures ignition times assumption consumption. Thereafter, entire solved numerically account effect various dimensionless parameters numerical solutions, graphs statistical measures skewness kurtosis concentrations temperature profiles presented in this work. Keywords: Two-step kinetics, reactant consumption, expressions, measures.
