Consider the reaction: CaCO3(s) CaO(s) + CO₂(g) Using standard thermodynamic data at 298K, calculate the entropy change for the surroundings when 1.91 moles of CaCO3(s) react at standard conditions. AS surroundings J/K
Consider the reaction 2NH3(g) + 3N₂O(g) → 4N2(g) + 3H₂O(g) for which AH = -879.5 kJ and AS = 288.1 J/K at 298.15 K. 1. Calculate the entropy change of the UNIVERSE when 2.388 moles of NH3(g) react under standard conditions at 298.15 K. ASuniverse J/K 2. Is this reaction reactant or product favored under standard conditions? 3. If the reaction is product favored, is it enthalpy favored, entropy favored, or favored by both enthalpy and entropy? If the reaction is reactant favored, choose 'reactant favored'.
Consider the reaction 2H₂O(1) + 2S0₂(g) 2H₂S(g) + 30₂(g) for which AH = 1.124x103 kJ and A5° = 390.7 J/K at 298.15 K. (1) Calculate the entropy change of the UNIVERSE when 1.581 moles of H₂O(1) react under standard conditions at 298.15 K. Suniverse J/K (2) Is this reaction reactant or product favored under standard conditions? (3) If the reaction is product favored, is it enthalpy favored, entropy favored, or favored by both enthalpy and entropy? If the reaction is reactant favored, choose 'reactant favored'.
For the reaction 3Fe2O3(s) + H₂(g) → 2Fe3O4 (8) + H₂O(g) AH = -6.0 kJ and AS = 88.7 J/K The standard free energy change for the reaction of 2.06 moles of Fe₂O3 (s) at 280 K, 1 atm would be kJ. This reaction is Assume that AH and AS are independent of temperature. favored under standard conditions at 280 K.
