This paper presents the development of the free convection 
boundary layer flow of a viscous and incompressible fluid past an 
impulsively started semi-infinite vertical cylinder with uniform heat 
and mass fluxes and chemically reactive species. The governing coupled 
nonlinear partial differential equations have been solved numerically 
using the finite-difference scheme of Crank-Nicolson type. Graphical 
results for the velocity, temperature, concentration, local and average 
skin friction, Nusselt number and Sherwood number profiles are illustrated 
and discussed for various physical parametric values. It is noted 
that due to the presence of first-order chemical reaction the velocity 
decreases with increasing values of the chemical reaction parameter.
