Explain why each of the following statements is incorrect. a. Entropy increases in all spontaneous reactions. Ot's not the entropy of system, but the entropy of universe, that increases in all spontaneous reactions. Olt's not the entropy of system, but the entropy of surroundings, that increases in all spontaneous reactions. Ot's incorrect because entropy decreases in all spontaneous reactions. b. Reactions with a negative free energy change (A,G° < 0) are product-favored and occur with rapid transformation of reactants to products. O4,G° tells only about equilibrium state, not about the rate it establishes. OReactions with a negative free energy change are reactant-favored. OIf A;G° is rather close to zero (but still negative), the transformation won't be rapid. c. All spontaneous processes are exothermic. Endothermic processes with positive entropy change can also be spontaneous. All spontaneous processes are endothermic. O Endothermic processes with negative entropy change can also be spontaneous.

Human DNA contains almost twice as much information as is needed to code for all the substances produced in the body. Likewise, the digital data sent from Voyager II contained one redundant bit out of every two bits of information. The Hubble space telescope transmits three redundant bits for every bit of information. How is entropy related to the transmission of information? What do you think is accomplished by having so many redundant bits of information in both DNA and the space probes?
Explain why each of the following statements is incorrect. (a) Entropy increases in all spontaneous reactions. (b) Reactions with a negative free energy change (rG 0) are product-favored and occur with rapid transformation of reactants to products. (c) All spontaneous processes are exothermic. (d) Endothermic processes are never spontaneous.
Entropy has been described as times arrow. Interpret this view of entropy.
A key component in many chemical engineering designs is the separation of mixtures of chemicals. (a) What happens to the entropy of the system when a chemical mixture is separated? (b) Are designs for chemical separation more likely to rely on spontaneous or nonspontaneous processes?
A certain reaction has negative value of both ∆H and ∆S. Therefore, the reaction must be spontaneous at all temperature cannot be spontaneous at any temperature cannot be spontaneous if the temperature is high enough cannot be spontaneous if the temperature is low enough has a positive free energy at any temperature

For the conversion of reactant A to product B, the change in enthalpy is 7.80 kJ·mol-1 and the change in entropy is 44.4 J·K-1·mol-1. Above what temperature, in Kelvin, does the reaction become spontaneous?___ K.
A curious blacksmith forge 1 kg of iron then dropped it into an insulated container that contains 50 liters of water. Before dropping the iron into the insulated container, the blacksmith measures the temperature of iron and water as 500 C and 20 C, respectively. This curious blacksmith is always interested in thermodynamics and tries to calculate equilibrium temperature and the total entropy change because of his/her action. What will be the equilibrium temperature and the total entropy change? Is this process reversible or irreversible? (Density and specific heat of water at 20 degrees C 995.10 kg/m^3 and 4.16 kJ/kg(C), respectively. Assume that the specific heat capacity of iron is 0.5 kJ/kg(C). )
