Assume that solutions of ethylbenzene : benzene behave ideally. a) Calculate the entropy of mixing if 40 g of ethylbenzene is mixed into 50 g of benzene.b) At room temperature (298 K), what is ΔmixG for mixing 40 g of ethylbenzene (PhEt) and 50 g of benzene (PhH)?c) Would you notice a temperature change associated with the process in parts a) & b)?d) Instead you mix 40 g of benzyl alcohol (PhMeOH) into 50 g of benzene (PhH). Let’s denote the difference between this process and the process in part b) as:ΔΔG = ΔmixG[ PhMeOH ∶ PhH ] − ΔmixG[ PhEt ∶ PhH ]What do you expect the sign of ΔΔG to be? ( ΔΔG < 0, ΔΔG ≈ 0, or ΔΔG > 0 )Briefly justify your answer.
I took out an ice cube from the -10°C freezer and wanted to add it to the drink, but was immediately called away and forgot to add it to the drink. When I came back, I saw that the ice cube had completely melted into water at a room temperature of 25°C. Assuming that the ice cube is exactly 2 mole, and regard this ice cube as a system, try to calculate the change of enthalpy and entropy (△H,△S) of the system. Let the heat capacity of water be 25 JK-1mol-1, the heat capacity of ice be 15 JK-1mol-1 and the heat of melting of ice △Ĥfus = 6 kJ/mol.

a) Formulate the second law of thermodynamics. b) Consider the statements below. Answer them and give brief explanations. a. An explosive (e.g. C7H5N3O6) reacts with oxygen, the result is CO2 (g), H2O (g) and N2 (g). Is there an increase or decrease of Entropy after the reaction occurred? b. Colloquially, people say that during the cold months of the year, the “cold” is creeping into the warmer house. Is this statement true considering the 2nd law?
