Solves a system of ordinary differential equations (ODE) in chemical kinetics: a CSTR with 3 components (A, B, C).

reactions
dCA⁄dt = -k1f CA + k1b CB
dCB⁄dt = k1f CA - k1b CB - k2f CB + k2b CC
dCC⁄dt = k2f CB - k2b CC

with (necessarily) the 3 initial charges given, by the (usual) Runge-Kutta 4.th order method.

The independent variable is time, t (minutes).

Draws graphs for the concentrations of A, B, and C.

The numerical values reported [Helmy, 2016] are, for t = 0.13 min and h = 0.01: 0.878, 0.110, 0.013 .
