4. This exercise will show an application of spanning sets and linear independence to Chemistry.
In industrial production or in theoretical Chemistry, you may encounter processes that need
multiple reactions in order to be achieved. Nevertheless, sometimes, the list of reactions is
longer than needed since it has redundant steps.
Although this sounds weird, it is not easy to differentiate which reactions are not needed. We
will work with the following reactions:
CO +02 → CO2
H2 + 02 → H2O
3
CH4 +O2 → CÓ + 2H2O
2
CHA + 202 → CO2+2H2O
(a) Write all of these reactions as equations. For example
1
CO +02 → CO2
can be written as
1
co +02 = CO,.
(b) Order the system of equations in such a way that each equation equal 0. For example,
1
CO +02 = CO2
should be written as
CO +02 - CO2 = 0.
(c) Consider each chemical compound as a variable. Taking that into account, write the
matrix associated to this system of equations. HINT: You should have 6 variables.
(d) For this matrix, find an spanning set for the row space.
(e) Remember that each of this vectors represents an equation. Write the equations that are
"independent" between them. HINT: You get three at the end.
