Some bacteria can obtain energy for growth by oxidizing ethanol, first to acetaldehyde and then acetic acid. Calculate ΔH° for the reaction:(a) C2H5OH(l) + ½O2(g)  ---> CH3CHO(l) + H2O(l)Use the following enthalpies of combustion: ΔcH°(C2H5OH, l) = -1362.8 kJ mol-1, ΔcH°(CH3CHO, l) = -886.8 kJ mol-1

Question

Some bacteria can obtain energy for growth by oxidizing ethanol, first to acetaldehyde and then acetic acid. Calculate ΔH° for the reaction:

(a) C2H5OH(l) + ½O2(g)  ---> CH3CHO(l) + H2O(l)


Use the following enthalpies of combustion:
ΔcH°(C2H5OH, l) = -1362.8 kJ mol-1,
ΔcH°(CH3CHO, l) = -886.8 kJ mol-1
