Webmore. With Hess's Law though, it works two ways: 1. You use the molar enthalpies of the products and reactions with the number of molecules in the balanced equation to find the change in enthalpy of the reaction. That's what you were thinking of- subtracting the change of the products from the change of the reactants. 2. WebExpert Answer 100% (4 ratings) Transcribed image text: 15. For the reaction FeCO3 (s) = FeO (s) + CO2 (g), AG is a function of temperature: AG = 78,073 – 26.2 T In T – 25.4 T + 3.45 x 10-?T? a) What is the expression for AS as a function of temperature? b) What is the expression for AH as a function of temperature? cuisinart classic stainless cookware review
What are the products of the decomposition of FeCO3?
WebGibbs energy, spontaneity, equilibrium For the reaction FeCO3 (s) = FeO (s) + CO2 (g), G is a function of temperature: G = 78,073 − 26.2 T ln T − 25.4 T + 3.45 x 10−2 T2 a) What is the expression for S as a function of temperature? b) What is the expression for H as a function of temperature? c) Calculate the value of G, S and H at 25oC. WebJun 2, 2024 · So, we can tell that the third reaction: Fe 3 O 4 (s) + CO → 3FeO (s) + CO 2 (g) ΔH= 21.8 needs to flipped to this. 3 FeO (s) + CO 2 → Fe 3 O 4 (s) + CO ΔH= -21.8 … WebAug 30, 2024 · In the reaction FeO + CO = Fe + CO2, the deltas are: delta H = (0+ -393) - (-266.5+ -110.5) = -16.3 KJ/mol. delta S = (27.2+213.8) - (197.9+54) = -10.9 J/mol/K Now at 1200 K, Go = -16.3 + (1200)(-10.9) = -3.23 I have ignored the effect of temperature on enthalpy as both the reactants and the products are at the same temperature. eastern orthodox fasting calendar
