Question
The enthalpy of formation for H2O(g), CO2(g), and C2H5OH(l), in kJ/mol, are given as follows:
DHfo[H2O(g)] = –241.8; DHfo[CO2(g)] = –393.5, and DHfo[C2H5OH(l)]
= –277.6
How much heat is produced if 2.00 mole of ethanol (C2H5OH) is completely combusted according to the following equation?
C2H5OH(l) + 3O2(g) --> 2CO2(g) + 3H2O(g);
(A) 2470 kJ
(B) 1230 kJ
(C) 1790 kJ
(D) 3580 kJ
