Question 8 O Given the following reactions: C4H10 () 13/2 O2(g) → 4 CO2(g) + 5 H₂O (9) Butane (MW 58 g/mol) C3H7OH (1) + 5 O2(g) → 3 CO2(g) + 4 H₂O (g) Propanol (MW = 60 g/mol) C2H4O2 (1) + 3 O2(g) → 2 CO2(g) + 2 H₂O (9) Acetic acid (MW = 60 g/mol) Butane has the highest %H by mass Butane produces the highest number of moles of CO2 (g) Based on the energies of the individual bonds of reactants and products, what is the principal reason that the butane combustion reaction is so much more exothermic? Butane consumes the highest number of moles of O2(g) AH° -2635 kJ/mol Butane is the best fuel AH° -1845 kJ/mol AH° = -785 kJ/mol
