Octan-1-ol is a liquid alcohol like the ones used in the experiment. In another bomb calorimetry experiment 1.4268 g of octan-1-ol is burned and the temperature of the calorimeter increased from 18.583C to 23.102C. The heat capacity of the calorimeter is 12.86 kJ C−1. Calculate the enthalpy of formation of octan- 1-ol in kJ/mol octan-1-ol. Compare this to the accepted value of −426.6 kJ mol−1.

Bomb calorimetry is a technique used to determine the enthalpy of combustion, usually in O2, of a chemical species. A known amount of compound is placed inside a fixed volume container that is, in turn, filled with oxygen at a high enough pressure to ensure complete combustion. The fixed-volume container (the 'bomb') is then inserted into a bucket containing a precisely known volume of water. The oxygen and compound are ignited, and the temperature change in the water is recorded....
