Problem 18

In Application 3, the solution (6, 6, 6, 1) was obtained by setting the free variable x4 = 1. (a) Determine the solution corresponding to x4 = 0. What information, if any, does this solution give about the chemical reaction? Is the term trivial solution appropriate in this case? (b) Choose some other values of x4, such as 2, 4, or 5, and determine the corresponding solutions. How are these nontrivial solutions related? 1
