         These are the same two reactions as in equation 5.1-20.

         (b)  Equations 5.1-22 to 5.1-26.
         Now we start with the transpose of the stoichiometric number matrix.

                 nutr=Transpose[nul
                 {{-I, -3,  1, 1, O},  I-1,  1, 0, -1, 111




                 0   0   0
                 0   0   0

         Now calculate a basis for the transpose of the conservation matrix from the transposed stoichiometric  number matrix.

                 TableForm[NullSgace [nutrl I

                 3    -   1  0   0  4
                 -11  0         2   0
                 1    1     4   0   0

         This looks different from equation 5.1-8, but yields 5.1-15 when RowReduction  is used.

                 TableFonn[RowReduce~NullSpace[nutrll1
                 1   0    0   1    2
                 0   1    0   3    2
                 0   0    1   -1   -1

          The rank of the conservation matrix is the number of components, which is 3.

                 (3,  5)


          The rank of the stoichiometric number matrix is equal to the number of independent reactions, which is 2.

                 Dimensions [nu]
                 (5,  2)

          (c)  Calculate the amounts  of the components  C, H, and 0 for a system containing  one mole of each of  the five species.
          Equation 5.1-27 yields
