# combustion of glucose enthalpy

The standard enthalpy changes of combustion of glucose and ethanol are given as -2820 and -1368 kJ mol ̄1 respectively. The standard molar entropy of H,(g) is Sº = The value corresponds to an exothermic reaction (a negative change in enthalpy) because the double bond in molecular oxygen is much weaker than other double bonds or pairs of single bonds, particularly those in the combustion products carbon dioxide and water; conversion of the weak bonds in oxygen to the stronger bonds in carbon dioxide and water releases energy as heat.

Q: 3. Now as one mole of combustion gives 2808 KJ of energy, Then the amount of glucose required to get energy of 137.5 J = 1        mol/2808000 J x 1837.5 = 6.54 x 10-4 moles, Mass of glucose = moles of glucose x molar mass of glucose. The enthalpy of combustion of glucose is - 2808 kJ mol" at 25°C. The combustion energy of glucose is used by the man to do work.
