Enthalpy is a thermodynamic quantity that describes the heat content of a system, that can not be measured directly. That's why we measure change in enthaply, measured in the units joules. The statement that e nthalpy change depends on the rate at which a substance is heated or cooled is false. Enthalpy change depends only on the following factors:

- physical state of reactants and products

- quantity of reactants

- allotropic modifications

- temperature and pressure
