R22 Pressure Enthalpy Chart
An enthalpy-entropy chart, also known as the H-S chart or Mollier diagram, plots the total heat against entropy, describing the enthalpy of a thermodynamic system. A typical chart covers a pressure range of .01-1000 bar, and temperatures up to 800 degrees Celsius.

In chemical reactions involving the changes in thermodynamic quantities, a variation on this equation is often encountered: ΔGchange in free energy = ΔHchange in enthalpy − TΔS(temperature) change in entropy. Example 1.1. Calculate ∆G at 290 K for the following reaction: 2NO(g) + O 2(g) → 2NO 2(g) Given. ∆H = -120 kJ.

Since enthalpy is a state function, a change in enthalpy does not depend on the pathway between two states. Hess's law: In going from a particular set of reactants to a particular set of products, the change in enthalpy is the same whether the reaction takes place in one step or in a series of steps.

Of course, the main issue here is how entropy changes during a process. This can be determined by calculation from standard entropy values (\ (S^ o\)) in the same way that enthalpy changes are calculated: ∑So products − ∑So reactants = ΔSorxn (6.5.2) (6.5.2) ∑ S p r o d u c t s o − ∑ S r e a c t a n t s o = Δ S r x n o.

This table lists the standard enthalpies (ΔH°), the free energies (ΔG°) of formation of compounds from elements in their standard states, and the thermodynamic (third-law) entropies (S°) of compounds at 298 K. The state of the compound is specified by the following symbols: (g) - gas (l) = liquid (s) - solid (aq) = aqueous solution

Mollier's H-S diagram (Enthalpy v Entropy) was a logical extension of the T-S diagram (Temperature v Entropy) first proposed by Gibbs, retaining the advantages of T-S diagrams but introducing several new advantages. A typical H-S Mollier diagram for a thermodynamic fluid such as steam is shown in Figure 1 . Figure 1.

An enthalpy-entropy chart, also known as the H-S chart or Mollier diagram, plots the total heat against entropy, [1] describing the enthalpy of a thermodynamic system. [2] A typical chart covers a pressure range of .01-1000 bar, and temperatures up to 800 degrees Celsius. [3]
Entropy Table
The Mollier diagram, also called the enthalpy (h) - entropy (s) chart or h-s chart, is a graphical representation of thermodynamic properties of materials. In general, it is a relationship between enthalpy (measure of the energy of a thermodynamic system), air temperature, and moisture content. Mollier Diagram Origins
