The enthalpy change. for a reaction can be calculated using the following equation: \[\Delta H=cm\Delta T\] \(\Delta H\) is the enthalpy change (in kJ or kJ mol-1) c is the specific heat capacity ...
Combustion reactions are often used to calculate the molar enthalpies of formation. For example, the standard molar enthalpy of combustion for methane can be expressed in terms of the standard molar enthalpies of formation of the reactants and products: ΔH o comb = 2 ΔH o f,water + ΔH o carbon dioxide - ΔH o f,methane - 2 ΔH o f,oxygen
Combustion efficiency is a measurement of how well the fuel being burned is being utilized in the combustion process. This is different from the efficiency number produced on the analyzer, which is reflective of the total amount of heat available from the fuel minus the losses from the gasses going up the stack.
CRC handbook standard combustion enthalpy for sucrose was -2,226,100 J/mol. ((my result-accepted)/ Accepted)(100) = % error ((-5,078,121.596-2,226,100)/2,226,100)x100= 128 % error
