Q ● ENTROPY AND FREE ENERGY Calculating dG from dH and dS 4PF, (g) + 10H₂(g) P4 (s) + 20HF (g) A chemical engineer is studying the two reactions shown in the table below. In each case, she fills a reaction vessel with some mixture of the reactants and products at a constant temperature of 53.0 °C and constant total pressure. Then, she measures the reaction enthalpy AH and reaction entropy AS of the first reaction, and the reaction enthalpy AH and reaction free energy AG of the second reaction. The results of her measurements are shown in the table. CH₂(g) + 20₂(g) → CO₂(g) + 2H₂O(g) ALEKS - Rafia Riaz - Learn Complete the table.
