Question
Suppose the sample had 1-mol% impurity with a heat of combustion 10% larger than that of the compound being studied, for example, napththalene or sucrose. Assuming that the measured heat of combustion of the mixture is a mole-fraction-weighted average of the components, what would be the effect of this impurity on the determined heat of formation of the particular compound.

determined heat of formation will be greater than the actual one
