Numerical methods for solving hyperbolic conservations laws usually involves
addition of extra dissipation. When the conservations laws are coupled to a
source term representing chemical reactions, this extra dissipation causes the
reaction fronts to move with an incorrect speed of propagation. It is studied
how the propagation speed depends on the order of approximation of the
numerical method. Remedies are presented which reduce the error in the speed.
