ΔE values obtained by bomb calorimetry can be converted to give accurate ΔH values.

Question

Quizplus · Accepted Answer

The relationship between ΔE and ΔH is ΔH = ΔE + PΔV, where PΔV is the work done by the system against external pressure. However, when bomb calorimetry is used, there is no volume change because the reaction takes place in a sealed container, so PΔV = 0, and ΔE = ΔH. Therefore, ΔE values obtained by bomb calorimetry can be directly used as ΔH values.
