2019 Q2

The thermochemical equation for the complete combustion of glucose is

C6H12O6 + 6O2 → 6CO2 + 6H2O ΔH = −2860 kJ mol−1

C6H12O6 + 3O2 → 6CO2 + 6H2O ΔH = −2011 kJ mol−1

C6H12O6 → 2C2H5OH + 2CO2 ΔH = −69 kJ mol−1

C6H12O6 → 2C3H6O3 ΔH = −120 kJ mol−1

2019 Q26 (51% correct ans)

The calibration factor of a bomb calorimeter was determined by connecting the calorimeter to a power supply. The

calibration was done using 100 mL of water, 6.5 V and a current of 3.6 A for 4.0 minutes. The temperature of the

water increased by 0.48 °C during the calibration.

4.20 g of sucrose underwent complete combustion in the bomb calorimeter. The temperature of the 100 mL of water

increased from 19.6 °C to 25.8 °C.

M(C12H22O11) = 342 g mol−1

The experimental heat of combustion of pure sucrose, in joules per gram, is

5.9 × 106

7.3 × 104

1.7 × 104

1.2 × 104
