Enthalpy (H) vs. Change in Enthalpy (∆H)
I understand that the change in enthalpy (∆H) is defined as the amount of heat (q) absorbed or released at constant pressure; but, what is the definition of the enthalpy of a system?
Re: Enthalpy (H) vs. Change in Enthalpy (∆H)
Enthalpy is the sum of internal energy in the system plus the product of pressure and volume at a certain time, while the change in enthalpy is the amount of heat gained or lost while under constant pressure. Another way to look at enthalpy change is that of the difference in bond energy from products and reactants! Hope this helps some!

The enthalpy of a system is the amount of heat energy it possesses. The equation is H = E + PV. Therefore, it is the sum of internal energy and the product of pressure and volume.
