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

If the rate of reaction werethen we would haveThis gives us -r_{A}= f(X). Consequently, we can use the methods discussed in Chapter 2 to size a large number of reactors, either alone or in series.

etc.

Again, these equations give us information about -r_{A}= f(X), which we can use to size reactors.Matching C_{A}versus X curves
