5. (For this problem, you don't need to write a function, but you do need to write a Matlab script). Balance the following stoichiometric equations by solving for the appropriate unknowns. You will need to write a balancing equation on each element, and then write it in the form Ax-b. Use Matlab to solve for x. Note that there are 5 unknowns, but only 4 elements on which to write balances. Therefore, we will assume a relationship between the amount of CO2 produced and O2 consumed. The ratio of moles CO2 produced to moles O2 consumed is called the respiratory quotient (RQ). Use this relationship to write a fifth equation, so that you have a system of 5 equations and 5 unknowns to solve. RQ 0.45 (b) Aerobic (with o) growth of S. cerevisiae (yeast) on ethanol. CH1.70No.149Oo40s is the yeast/biomass RQ 0.66 (c) Production of E. coli (bacteria) using glycerol and ammonia: RQ 0.44
