Calculate the entropy change for a process in which 3.00 moles of liquid water at 0oC is mixed with 1.00 mole of water at 100.oC in a perfectly insulated container. (Assume that the molar heat capacity of water is constant at 75.3 J K-1mol-1.)
Answer to relevant QuestionsCalculate the change in entropy that occurs when 18.02 g of ice at 210.0oC is placed in 54.05 g of water at 100.0oC in a perfectly insulated vessel. Assume that the molar heat capacities for H2O(s) and H2O(l) are 37.5 ...Calculate ΔSsurr for the following reactions at 25oC and 1 atm. Ethanethiol (C2H5SH; also called ethyl mercaptan) is commonly added to natural gas to provide the “ rotten egg” smell of a gas leak. The boiling point of ethanethiol is 35ºC and its heat of vaporization is 27.5 kJ/ mol. ...Of the functions ΔHo, ΔSo, and ΔGo, which depends most strongly on temperature? When ΔGo is calculated at temperatures other than 25oC, what assumptions are generally made concerning ΔHo and ΔSo? A reaction at constant T and P is spontaneous as long as ΔG is negative; that is, reactions always proceed as long as the products have a lower free energy than the reactants. What is so special about equilibrium? Why ...
