- Is the following reaction spontaneous as written? Explain. Do whatever calculation is needed to answer the question. SO2(g)+H2(g)H2S(g)+O2(g)arrow_forwardDescribe the energy and entropy changes that occur in the following processes, and indicate whether the processes are spontaneous under the conditions stated: a.On a cold day, water freezes. b.A container of water at 40C cools to room temperature. c.The odor from an open bottle of perfume spreads throughout a room.arrow_forwardConsider the system shown in Figure 16.9. What is the change in entropy for the process where the energy is initially associated with particles A and B, and the energy is distributed between two particles in different boxes (one in A-B, the other in C-D)?arrow_forward
- The free energy of formation of one mole of compound refers to a particular chemical equation. For each of the following, write that equation. a KBr(s) b CH3Cl(l) c H2S(g) d AsH3(g)arrow_forwardUse the standard entropy data in Appendix G to determine the change in entropy for each of the reactions listed in Exercise 16.34. All the processes occur at the standard conditions and 25 C.arrow_forwardCalculate H and G for the following reactions at 25C, using thermodynamic data from Appendix C; interpret the signs of H and G. a Al2O3(s)+2Fe(s)Fe2O3(s)+2Al(s) b COCl2(g)+H2O(l)CO2(g)+2HCl(g)arrow_forward
- What is a spontaneous process? Give three examples of spontaneous processes. Give three examples of nonspontaneous processes.arrow_forwardWhich contains greater entropy, a quantity of frozen benzene or the same quantity of liquid benzene at the same temperature? Explain in terms of the dispersal of energy in the substance.arrow_forwardFor the reaction SnO2(s)+2CO(g)2CO2(g)+Sn(s)calculate the temperature at which G =0.arrow_forward
- Pick the example with the highest entropy from each of the following sets. Explain your answers. a.Solid ice, liquid water, or steam b.Leaves on a tree, fallen leaves blown about on the ground, fallen leaves raked and placed in a basket c.A stack of sheets of paper, a wastebasket containing sheets of paper, a wastebasket containing torn and crumpled sheets of paper d.A 0.10M sugar solution, a 1.0M sugar solution, a 10.0M sugar solution e.A banquet table set for dinner, a banquet table during dinner, a banquet table immediately after dinnerarrow_forwardCalculate S for the reaction C2H4(g)+3O2(g)2CO2(g)+2H2O(l) See Table 18.1 for values of standard entropies. Does the entropy of the chemical system increase or decrease as you expect? Explain.arrow_forwardThe free energy of formation of one mole of compound refers to a particular chemical equation. For each of the following, write that equation. a MgO(s) b COCl2(g) c CF4(g) d PCl5(g)arrow_forward
