Document Summary

I < 0 for reactants above: co2 = 1 o2 = -1/2 co = -1. => vector of rxn coefficients can be rescaled ex: above rxn. 2co2 2co + o2 ( i --> - i , reverse rxn) Chen thermo page 1 initial mixture rxn to eqbm final mixture: = # moles of i, initial. Mole fraction: yi = ni/n = {# moles of species i}/{total # moles: total, initial. Ex: for co + (1/2)o2 co2 -------------> = -1/2. Ex: co + (1/2)o2 co2: = 2 mol no2. Nco: = 5 mol nco2, = 3 mol. Chen thermo page 2 can make a table o. 2 - x yi (2 - x)/(10 - (1/2)x) Consider a system w/ fixed t + p in which rxn can occur. Question: what"s the eqbm composition @ specified t + p for specific initial composition. What"s the eqbm extent of rxn: + ix.
