Stoichiometric Tables

Using stoichiometry, we set up all of our equations with the amount of reactant A as our basis.

 [a liquid phase reaction, or a gas phase reaction in a rigid (e.g., steel) reactor] etc.

 etc.   If the rate of reaction were then we would have This gives us -rA = f(X). Consequently, we can use the methods discussed in Chapter 2 to size a large number of reactors, either alone or in series.

Gas Phase Flow System:

 etc.   Again, these equations give us information about -rA = f(X), which we can use to size reactors.
Matching CA versus X curves
