Question

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 =
