In today's class we carried out a lab to demonstrate Hess' Law and accordingly increase our understanding of said law. The aim of the lab was to determine the enthalpy change of a particular reaction. However, since the actual reaction is immeasurable, we needed to combust two separate compounds in order to determine the total enthalpy change of the reaction.
Hess' Law states that the route taken doesn't impact the final enthalpy change between reactants and products. Therefore, utilizing two separate reactions, we were able to find the enthalpy change of a single reaction.
We also continued to work on our lab reports in class. The aim of the lab was to determine the relationship between the enthalpy change of combustion of alcohols and their carbon chain length.
