20. The sublimation of solid carbon dioxide is a spontaneous process. Predict the sign (+,-, or 0) of AG", AH", and AS, respectively. 21. Calculate AG for the following reaction at 298 K. 2PbS(s) + 3O2(g) → 2PbO(s) + 25O2(g) AH°= -844 kJ ASO= -165 J/K If the reaction is not spontaneous under standard conditions at 298K, at what temperature (if any) would the reaction become spontaneous?

Question 6 Not answered Marked out of 1.00 If the above reaction could be done at 3399 K, what would be your estimate for AGº (in kJ) at this elevated temperature? Use AG° =AH° -TAS® and assume AH° and 4Sº are independent of temperature. P Flag question (Theº is included because it is still for standard conditions, that is, 1 atm for gases and 1 molar for concentrations.) Answer: What is Agrº (in kJ) at 2268 K for the following...
