In order to be able to find the time dependent concentration of each of the species, the reaction rate of the reactions is needed. The reaction rate of a chemical reaction aA + bB − > dD + eE , is given by: RR s = k s · c a A · c b B (5.13) with RR s , the reaction rate for reaction s in mol/ls, k s the reaction rate constant and c i the concentration of specie i in mol/l. The production rate of each of the species is then

for A: − a · RR s for B: − b · RR s for C: + c · RR s for D: + d · RR s
