Nitrogen Enthalpy, Internal Energy and Entropy vs. Temperature
The Mollier diagram, shown in Figure A-1 , is a chart on which enthalpy (h) versus entropy (s) is plotted. It is sometimes known as the h-s diagram and has an entirely different shape from the T-s diagrams. The chart contains a series of constant temperature lines,a series of constant pressure lines, a series of constant moisture or quality.
Enthalpy Entropy (hs) or Mollier Diagram Engineers Edge
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.
Enthalpy Entropy (hs) or Mollier Diagram
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

Details. Enthalpy and entropy are calculated using the Peng-Robinson equation of state (EOS) for a real gas and the ideal gas law for an ideal gas:. where is in kJ/mol and is in kJ/[mol K]; the superscript represents an ideal gas, the subscript refers to the reference state, and and are the enthalpy and entropy departure functions for a real gas calculated from the Peng-Robinson EOS, while.

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

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]

Enthalpy of Combustion. Standard enthalpy of combustio n (\(ΔH_C^\circ\)) is the enthalpy change when 1 mole of a substance burns (combines vigorously with oxygen) under standard state conditions; it is sometimes called "heat of combustion." For example, the enthalpy of combustion of ethanol, −1366.8 kJ/mol, is the amount of heat produced when one mole of ethanol undergoes complete.

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.
