Use the standard free energy of formation data to determine the free energy change for each of the following reactions, which are run under standard state conditions and 25 °C. Identify each as either spontaneous or nonspontaneous at these conditions. a. MnO₂ (s) → Mn (s) + O₂ (g) b. H₂(g) + Br2 (1)→ 2HBr (g) c. Cu (s) + S (g) → CuS (s) d. 2LiOH (s) + CO₂ (g) → Li₂CO3 (s) + H₂O (g)
Chemistry Small amounts of Fe(CO)5(l) usually form in steel tanks containing pressurized CO(g). You worked out the thermodynamics of this in question 1b. At what temperature (oC) will the formation of Fe(CO)4 become non-spontaneous? Show your work. b) A similar reaction occurs to make Ni(CO)4(l) with Gorxn = −38 kJ/mol, Horxn = −230 kJ/mol, and Sorxn = −480 J/Kmol. High pressure reactors use a thin disk of metal as a safety mechanism that will rupture and release gasses if the pressure in the reactor gets too high. If one was using CO gas, which disk (Fe or Ni) would be more likely to prematurely fail due to the metal being dissolved away by CO? Briefly explain why.
Consider the reaction described by the chemical equation shown. 3 C,H,(g) → C,H,(1) AHan = -633.1 kJ Use the data from the table of thermodynamic properties to calculate the value of ASxn at 25.0 °C. ASPxn = J.K-!
