IB Chemistry Topic 5.2 & 5.3: Hess's Law & Bond Enthalpies
Показать описание
In this video, Hess’s law is introduced as a new way to calculate enthalpy changes, followed by practice problems. Then, the concept of average bond enthalpy and its related formula are introduced, before discussing how this differs from literature values. Finally, bond enthalpy is related to how ozone and diatomic oxygen behave in the atmosphere.
