9. For the following reactions, predict whether they will tend to be spontaneous at high, low, ali temperatures, or non-spontaneous at any temperature (10 points) a) 2A(g) + 3B(9) C(g) + D(1), AH < 0 b) A() + B() (1) + D(s) AH > 0 c) A(s) + B(1) ► 20(1), AH < 0 d) 2A(s) B(s) + C(I), AH > 0
16. For the following reactions, predict whether they will tend to be spontaneous at either high or low temperatures, or at all temperatures, or at no temperature (10.0 points) a) H2(g) + 12(g) → 2HI(g) AH = -220 kJ b) 3S2(g) → 253(g) AH = +227 kJ c) H2O(l) → H2O(g) AH = +44 kJ d) H2(g) + '/gS8(g) → H2S(1) AH = -247 kJ
answer 13 and 14 please
12. The space shuttle uses the combustion of hydrogen with oxygen to power the main rockets. Use the data in the appendix to calculate the standard entropy change, Aso, for the combustion of 1 mole of hydrogen (note: all reactants and products are in the gaseous state). Be sure to provide the balanced equation for the combustion. (10 points). 13. When an ionic solid (like NaCl) dissolves in water the molecules of water separate, surround...

State whether following reactions are spontaneous at all temperatures, low temperatures, high temperatures or not spontaneous at any temperatures. (a) N2(g) + 3 F2(g) + 2 NF3(g) AH = -249 kJ (b) N()+ 3Cl2(g) → 2 NC13(g) AH = 460 kJ (e) NF4(8) 2 NF2(g) AH = 85 kJ
Predict whether AS will be positive or negative for reactions (a) and (b): a. 2 HgO(s) → 2Hg(1) + O2(g) AS b. 2 CH (B) + 70(8) ► 4 CO2(g) + 6 H2O(1) AS Choose one of the above reactions a OR b. Calculate the AH® for your chosen reaction using information from the table below. AH = Using your answers above, predict under what temperature (temp) conditions (high temp or low temp) where this reaction will be spontaneous, or...
2.A certain compound undergoes a solid + liquid phase transition at -25.5°C. The entropy change AS, associated with the phase transition at this temperature is 53.8 J mor' K". What is the amount of heat energy. 9, that is absorbed to give this value for AS? (8 points) 8. Use the data in the appendix to calculate the standard entropy change, ASo, for the combustion of 1 mole of methane, CHe() (note: all reactants and products are in the gaseous...
6. (3 points) For each of the following reactions, predict the sign (positive or negative) for the AS and AH values. Then determine when the reaction will be spontaneous (always, never, at high temperatures, or at low temperatures). a. CH4(g) + 202 (g) → CO2 (g) + 2H20 (g) b. 4H3PO4(s) - P010 (s) + 6H20 (1) c. HCI (g) + NH3(g) → NH4Cl (s)
the first one is supposed to be meant spontaneous. thanks
