Document Summary

We want to make the most out of the least (and least expensive) raw material with fewest byproducts systematic method for solving multiple reaction pathways. Vik = stoichiometric coefficient of compound i in reaction k. Sample rxn: a + b c 1, c + d e 2. Steps: 1) balance rxns for all k steps, 2) list all i compound in a column. 0 want no net intermediate: 3) for each rxn, k, write down vik, 4) sum across rows to get net stoichiometric coefficient, 5) find k for rxns involving a given compound to get 0 generation/consumption. A + b 2c 1 1. C + d e 2 2. 1 2 + 2(-1) = 0. Ammonia and antibiotics reason for why population . R1: h2o + ch4 co + 3h2. R2: co + h2o co2 + h2. R3: n2 + 3h2 2nh3: step 2. Co: 1(+1) + 2(-1) + 3(0) = 0 1- 2 = 0.
