Hello, I need help with the blank section
![Be sure to answer all parts.
The U.S. requires automobile fuels to contain a renewable component. The fermentation of glucose
from corn produces ethanol, which is added to gasoline to fulfill this requirement:
C6H12O6(s) → 2 C₂H₂OH(1) + 2 CO2(g)
Calculate AH, AS° and AG° for the reaction at 25°C. Is the spontaneity of this reaction dependent
on temperature?
