Substance or Ion. Hfo (kJ/mol). Gfo (kJ/mol). So (J/molK). Al(s). 0. 0. 28.3. Al3+(aq). 531. 485. 321.7. AlCl3(s). 705.6. 630.1. 109.3. Al2Cl6(g). 1291. The standard Gibbs free energy of formation of a compound is the change of Gibbs free energy that accompanies the formation of 1 mole of a substance in its standard state from its constituent elements in their standard states (the most stable form of the element at 1 bar of pressure and the specified temperature, usually 298. The table below lists the Standard Gibbs function of formation for several elements and chemical compounds and is taken from Lange’s Handbook of Chemistry. Note that all values are in kJ/mol. Go and the equilibrium constant for a chemical reaction is illustrated by the data in the table below.

delta g values table 2NIST-JANAF table deltaG standard formation values at 5400 K for N(g), O(g) and NO(g) are 113.817 kJ/mol, -108.155 kJ/mol and 23.568 kJ/mol. 3.2 Table of entropy data & comments and 3.3 Entropy values, entropy changes and feasibility of a physical change. You could calculate it as, G G_products G_reactants But this will only be valid for the temperature which your table has its G values calculated in.

Its magnitude and sign are listed in the table of Thermodynamic Data under the standard enthalpy of formation column, and has the value -286 kJ/mol. When viewing a cell reduction potential table, the higher the cell is on the table, the higher potential it has as an oxidizing agent. Table 1 provides sample values of standard enthalpies of formation of various compounds. Consequently, Br2(g) has a nonzero standard enthalpy of formation.

To see how DG values can be used to predict how reactions will go, consider the four cases you encountered in the Entropy Module: 1. Thus, it is like an exothermic reaction with a negative value of DE or DH. A reaction with a negative DG is called exergonic to emphasize this. Values of delta for exceedance probability and skewness (Extract from Australian Rainfall and Runoff Book IV, Table 2.4).
