calculate the Gibbs free energy of formation of BiF5 at 298 K.
Is the formation of BiF5 from the elements spontaneous?
Assuming that neither standard enthalpy changes of formations (∆Hof) nor standard molar entropies (So) depend upon temperature, estimate using the Table of Thermodynamic Data : (a) the standard Gibbs free energy change for the reaction that forms rhombic sulfur at 600 K, and (b) the temperature (in oC) at which reaction will stop formation of products:
2H2S(g) + SO2(g) → 3S(rhombic, s) + 2H2O(g)
Round off your answers to the nearest integer. Report the temperature in oC. and enter them with correct units:
(a)∆Gorxn =
(b) T =
