2. Hydrogen sulfide decomposes according to the following reaction: 2H2S(g) 2H2(g) + S2(g) For this reaction at 298 K, ASrxn = 86.1 J/K*mol, AHrxn = 160.5 kJ/mol, and AGrxn = 146.1 kJ/mol. Calculate the AGrxn , in kJ/mol, at 717C. 3. For the following reaction, AS sys= 198.9 in J/K, calculate the AS univ, in J/K at 25.0 C given the following data: 2 PbO(s) + C(s) + CO2(g) + 2 Pb(s) PbO(s) AH'= -218.9 kJ/mol CO2(g) AH'= -395.4 kJ/mol
