Definition of errors in enthalpy of combustion
Check what you remember
Read the wording for your board, then hide it and explain errors in enthalpy of combustion in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
An experimental enthalpy of combustion from a calorimeter comes out less exothermic than the data book value, and incomplete combustion is a standard mark scheme answer for that discrepancy, alongside heat loss.
