Figure 6.7 Temperature-interval diagram and enthalpy-mapping diagram for a moderately sized industrial problem.

An energy diagram (enthalpy) called the Bom-Haber cycle is used like a road map to show all the possible side reactions that can occur like with any road trip, there are multiple ways to get to a destination. Flooding on the road, for example, can cause you to take a different route this is analogous to the way the environment affects the reaction dynamics. 

Examine the enthalpy-composition map for G-H mixtures at 1 atm. The dashed lines in the liquid region and the vapor region show the temperature at a given composition and enthalpy. The dashed lines in the liquid-vapor region are tie lines. Unlike the previous phase diagrams, the tie lines in the liquid-vapor region are not horizontal. Liquid and vapor at equilibrium have the same temperature but not the same enthalpy.
