Learning Goal: To understand how to use Hess's law to find the enthalpy of an overall reaction. The change in enthalpy, ΔH, is the heat absorbed or produced during any reaction at constant pressure. Hess's law states that ΔH for an overall reaction is the sum of the ΔH values for the individual reactions. For example, if we wanted to know the enthalpy change for the reaction 3Mn+3O2→3MnO2 we could calculate it using the enthalpy values for the following individual...
