Yeasts and other organisms can convert glucose (C6H12O6) to ethanol or acetic acid. Calculate the reaction enthalpy ∆rH when 1 mol of glucose is oxidized to (a) ethanol or (b) acetic acid by the following path at 298 K:

You can ignore all heats of solution of products or reactants. The overall reactions are

C6H12O6(s)→2 C2H5OH (l) + 2 CO2(g)

2O2(g) + C6H12O6(s) →

2 CH3COOH (l) + 2 CO2(g) + 2H2O(l).

a. Calculate the ∆rH for the complete combustion of glucose to CO2(g) and H2O(l).
