Olanrewaju , On the Induction Period for One-Step and a Two-Step Arrhenius Reaction, Research Journal of Applied Sciences, Volume 2,Issue 6, 2007, Pages 737-739, ISSN 1815-932x, rjasci.2007.737.739, (https://makhillpublications.co/view-article.php?doi=rjasci.2007.737.739) Abstract: In thisstudy, we investigate the induction period for one-step and a two step Arrhenius reaction to give further insight into the theory of combustion under reasonable and physical conditions. We compare the ignition time for one-step and a two -step reaction under the same necessary and sufficient conditions of explosion. Numerical solution was constructed for the resulting problem using finite difference scheme. Keywords: Induction period;one-step reaction and two-step reactions
