Kinetics for Windows is a PC based software which will write your
differential equations and solve them.  It has an easy to use graphical user
interface and gives you a plot of concentration vs. time.  The user can add
up to 100 reversible reactions, with their starting concentrations and the
rate contstants, and the program does the rest.  Contact ARSoftware
([email-masked]).  Leave an address or fax number if you'd like more information.
