As the rate of every reaction is known, the production and consumption of each of the species can be calculated. According to the reactions one can find the following production rates, R i , of each specie expressed in mol/ls: • PR e − = − RR 1 − RR 2 − RR 3 − RR 4 − RR 6 − RR 7 − 2 . ∗ RR 8 + RR 12 − RR 13 − RR 14 − RR 28 − RR 38 − RR 43 − RR 47 − RR 48 + E e − • PR H = RR 1 + RR 2 − 2 . ∗ RR 5 − RR 12 − RR 13 − RR 17 + RR 18 − RR 20 − RR 21 − RR 26 − RR 27 − RR 31 + E H • PR OH = − RR 3 + RR 4 − 2 ∗ RR 9 − RR 10 − RR 11 + RR 14 − RR 17 − RR 18 − RR 19 + RR 20 + RR 31 +2 ∗ RR 34 − RR 35 − RR 36 + RR 37 + RR 44 + RR 45 + E OH • PR H + = − RR 2 − RR 15 + RR 16 + RR 22 − RR 23 − RR 39 + RR 46 + E H + • PR OH − = RR 1 + RR 3 + RR 4 + 2 ∗ RR 8 + RR 11 − RR 12 + RR 13 + 2 ∗ RR 14 − RR 15 + RR 16 + 2 ∗ RR 25 + RR 28 − RR 29 + RR 32 − RR 36 + RR 37 + RR 42 + RR 45 + RR 47 + RR 48 − RR 49 + RR 50 − RR 53 + RR 54 − RR 55 + RR 56 − RR 57 + RR 58 − 2 ∗ RR 59 + 2 ∗ RR 60 + E OH − • PR O 2 = − RR 7 + RR 10 + RR 11 − RR 21 + RR 24 + RR 25 + RR 30 + RR 33 + RR 39 + RR 41 + RR 45 + E O 2 • PR O − 2 = RR 7 − RR 11 + RR 22 − RR 23 − 2 ∗ RR 25 − RR 27 − RR 28 − RR 33 + RR 35 − 2 ∗ RR 39 − RR 43 − RR 45 − RR 48 + E O − 2 • PR H 2 = RR 5 + RR 8 + RR 13 − RR 18 + RR 31 + E H 2 51
