  • Determination of Enthalpy

    Determining the Enthalpy of a Chemical Reaction All chemical reactions involve an exchange of heat energy; therefore, it is tempting to plan to follow a reaction by measuring the enthalpy change (∆H). However, it is often not possible to directly measure the heat energy change of the reactants and...
