10.5.1 Enthalpy diagrams. Enthalpy diagrams are a representation of the relative internal energy of a system before and after a reaction. Horizontal lines are drawn to show the energy of the system at a particular time. The nature of the system which has that energy is written on the line.

An enthalpy diagram is graphed with the enthalpy on the y axis and the time, or reaction progress, on the x axis. Examining the Diagram Let's look at the elements of this enthalpy diagram.

SCH4U Enthalpy Diagrams
Enthalpy Diagrams: The enthalpy relationships involved in adding thermochemical equations are most easily visualized by means of an enthalpy diagram, such as the one below.
HESS'S LAW AND ENTHALPY CHANGE CALCULATIONS
You can do calculations by setting them out as enthalpy diagrams as above, but there is a much simpler way of doing it which needs virtually no thought.
On the diagram, lines of constant pressure, constant temperature and volume are plotted, so in a two phase region, the lines of constant pressure and temperature coincide. Thus, coordinates on the diagram represent entropy and heat.
Enthalpy ˈ ɛ n θ əl p i , a property of a thermodynamic system, is equal to the system's internal energy plus the product of its pressure and volume. In a system enclosed so as to prevent matter transfer, for processes at constant pressure, the heat absorbed or released equals the change in enthalpy.
