- Define the following: a. spontaneous process b. entropy c. positional probability d. system e. surroundings f. universearrow_forwardIdentify each of the processes listed as spontaneous or nons-pontaneous. For each nonspontaneous process, describe the corresponding spontaneous process in the opposite direction. (a) A group of cheerleaders builds a human pyramid. (b) Table salt dissolves in water. (c) A cup of cold coffee in a room becomes steaming hot. (d) Water molecules in the air are converted to hydrogen and oxygen gases. (e) A person peels an orange, and you smell it from across the room.arrow_forwardConsider two perfectly insulated vessels. Vessel 1 initially contains an ice cube at 0C and water at 0C. Vessel 2 initially contains an ice cube at 0C and a saltwater solution at 0C. Consider the process H2O(s) H2O(l). a. Determine the sign of S, Ssurr, and Suniv for the process in vessel 1. b. Determine the sign of S, Ssurr, and Suniv for the process in vessel 2. (Hint: Think about the effect that a salt has on the freezing point of a solvent.)arrow_forward
- Cells use the hydrolysis of adenosine triphosphate, abbreviated as ATP, as a source of energy. Symbolically, this reaction can be written as ATP(aq)+H2O(l)ADP(aq)+H2PO4(aq) where ADP represents adenosine diphosphate. For this reaction, G =30.5 kJ/mol. a. Calculate K at 25C. b. If all the free energy from the metabolism of glucose C6H12O6(s)+6O2(g)6CO2(g)+6H2O(l) goes into forming ATP from ADP, how many ATP molecules can be produced for every molecule of glucose?arrow_forwardSome water is placed in a coffee-cup calorimeter. When 1.0 g of an ionic solid is added, the temperature of the solution increases from 21.5C to 24.2C as the solid dissolves. For the dissolving process, what are the signs for Ssys, Ssurr, and Suniv?arrow_forwardFor the reaction at 298 K, 2NO2(g)N2O4(g) the values of H and S are 58.03 kJ and 176.6 J/K, respectively. What is the value of G at 298 K? Assuming that H and S do not depend on temperature, at what temperature is G = 0? Is G negative above or below this temperature?arrow_forward
- The free energy for a reaction decreases as temperature increases. Explain how this observation is used to determine the sign of either H or S.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_forwardWhat is the third law of thermodynamics? What are standard entropy values, S, and how are these S values (listed in Appendix 4) used to calculate S for a reaction? How would you use Hesss law to calculate S for a reaction? What does the superscript indicate? Predicting the sign of S for a reaction is an important skill to master. For a gas-phase reaction, what do you concentrate on to predict the sign of S? For a phase change, what do you concentrate on to predict the sign of S? That is, how are Ssolid, Sliquid, and Sgas related to one another? When a solute dissolves in water, what is usually the sign of S for this process?arrow_forward
- Consider the reaction of 1 mol H2(g) at 25C and 1 atm with 1 mol Br2(l) at the same temperature and pressure to produce gaseous HBr at these conditions. If this reaction is run in a controlled way to generate work, what is the maximum useful work that can be obtained? How much entropy is produced in this case?arrow_forwardFor the reaction NO(g)+NO2(g)N2O3(g) , use tabulated thermodynamic data to calculate H and S. Then use those values to answer the following questions. (a) Is this reaction spontaneous at 25°C? Explain your answer. (b) If the reaction is not spontaneous at 25°C, will it become spontaneous at higher temperatures or lower temperatures? (c) To show that your prediction is accurate, choose a temperature that corresponds to your prediction in part (b) and calculate G . (Assume that both enthalpy and entropy are independent of temperature.)arrow_forwardGiven the values of H and S, which of the following changes will be spontaneous at constant T and p? a.
