Method 2: Calculating AG from AH and Soº data. ● If you have AHP and So data, you can use Hess' Law and calculate AH° and AS, then calculate AG°. Ex. Calculate AG for the reaction below at 25 °C, given 4NO(g) 2N₂O(g) + O2(g) Substance NO(g) N₂O(g) O₂(g) AH (kJ/mol) +90.37 +81.57 0.00 So (J.mol-¹K-¹) 210.6 220.0 205.0
