###### Problem Details

Find the standard heat of formation (ΔH f) for butanol, C4H10O(l) given the following combustion reaction and information below:

2C4H10O (l) + 12O2 (g) → 8CO2 (g) + 10H2O (l)     ΔH = -2676 kJ

H2O (l)  ΔH f = -285.8 kJ/mol

CO2 (g) ΔHf = -393.5 kJ/mol

a. + 832.5 kJ

b. - 998.4 kJ

c. - 1665 kJ

d. - 1483 kJ

e. - 378.9 kJ
