(a)
Interpretation:
The reason needs to be explained for a spontaneous change in the reaction, the change in entropy in a system is not always a suitable criterion.
Concept introduction:
Entropy is the measurable quantity which indicates the randomness of the system. The gaseous components have high entropy whereas solid substances have less entropy. According to Second law of
The Gibb’s equation of thermodynamic purposed a relation between

Concept introduction:
Entropy is the measurable quantity which indicates the randomness of the system. The gaseous components have high entropy whereas solid substances have less entropy. According to Second law of Thermodynamics, the entropy of universe will always increase. In other words, the changes in the entropy can never be negative.
The Gibb’s equation of thermodynamic purposed a relation between

- What happens to the entropy of the universe during a spontaneous process?arrow_forwardHow does the second law of thermodynamics explain a spontaneous change in a system that becomes more ordered when that process is exothermic?arrow_forwardFor the process A(l) A(g), which direction is favored by changes in energy probability? Positional probability? Explain your answers. If you wanted to favor the process as written, would you raise or lower the temperature of the system? Explain.arrow_forward
- On the basis of your experience, predict which of the following reactions are spontaneous. (a) CO2(s)CO2(g) at 25°C (b) NaCl(s)NaCl(l) at 25°C (c) 2NaCl(s)2Na(s)+Cl2(g) (d) CO2(g)C(s)+O2(g)arrow_forwardWhat is meant by the standard free-energy change G for a reaction? What is meant by the standard free energy of formation Gf of a substance?arrow_forward10.104 (a) When a chemical bond forms, what happens to the entropy of the system? (b) Thermodynamically, what allows any bond formation to occur? (c) What do your answers to parts (a) and (b) suggest must be true about the formation of chemical bonds for the octet rule to hold?arrow_forward
- The biological oxidation of ethanol, C2H5OH, is also a source of Gibbs free energy. (a) Does the oxidation of 1 g ethanol give more or lessenergy than the oxidation of 1 g glucose?(Hint:Writethe balanced equation for the production of carbondioxide and water from ethanol and oxygen, and useAppendix J.) (b) Comment on potential problems of replacing glucosewith ethanol in your diet.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_forwardConsider the reaction of 2 mol H2(g) at 25C and 1 atm with 1 mol O2(g) at the same temperature and pressure to produce liquid water 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_forward
- A reaction has H298=100 kj/mol and S298=250 J/mol K. Is the reaction spontaneous at room temperature? If not, under what temperature conditions will it become spontaneous?arrow_forwardDescribe how the standard entropy of hydrogen gas at 25C can be obtained from heat measurements.arrow_forwardAppendix J lists standard molar entropies S, not standard entropies of formation rS. Why is this possible forentropy but not for internal energy, enthalpy, or Gibbsfree energy?arrow_forward
