%0 Journal Article %T Velocity of front propagation in 1-dimensional autocatalytic reactions %A Warren C. %A Somfai E. %A Sander L.M. %J Brazilian Journal of Physics %D 2000 %I Scientific Electronic Library Online %X We study a discrete model of the irreversible autocatalytic reaction A + B -> 2A in one dimension. Looking at the dynamics of propagation, we find that in the low-concentration limit the average velocity of propagation approaches v = theta/2, where theta is the concentration, and, in the high concentration limit, we nd the velocity approaches v = 1 - e-theta/2. %U http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0103-97332000000100016
