Question $4(15$ pts$).$ Glucose $(C_6{H}_{12}{O}_6)$ in the grain is converted into ethanol $(C_2{H}_{5}OH)$ and propenoic acid $(C_2{H}_{3}C{O}_{2}H)$ during the fermentation of grain by the following reactions:

$C_6{H}_{12}{O}_{6}2C_2{H}_{5}OH+2C{O}_2$

$C_6{H}_{12}{O}_{6}2C_2{H}_{3}C{O}_{2}H+2H_{2}O$

The feed to the flow reactor in which the fermentation process occurs contains $3500k\frac{g}{h}$ of $12wt.\%$ glucose$/$water solution. The outlet stream from the reactor contains $120k\frac{g}{h}$ of carbon dioxide together with $90k\frac{g}{h}$ of unreacted glucose. What are the weight percentages of ethyl alcohol and propenoic acid in the exit stream of this reactor?
