To determine the enthalpy of a reaction, one can use Hess's Law or measure the heat released or absorbed during the reaction using a calorimeter. Hess's Law involves adding or subtracting the enthalpies of known reactions to find the enthalpy of the desired reaction. Calorimetry involves measuring the temperature change of the reaction and using it to calculate the enthalpy change.
