a. Use the equation in Exercise 86 to determine ΔHo and ΔSo for the autoionization of water: H2O(l) ⇌ H+(aq) + OH-(aq)
b. Estimate the value of ΔGo for the autoionization of water at its critical temperature, 374oC.
Answer to relevant QuestionsThe equilibrium constant K for the reaction 2Cl(g) ⇌ Cl2(g) was measured as a function of temperature (in kelvins). A graph of ln(K) versus 1/ T for this reaction gives a straight line with a slope of 1.352 × 104 K and a ...Consider 1.00 mole of CO2(g) at 300. K and 5.00 atm. The gas expands until the final pressure is 1.00 atm. For each of the following conditions describing the expansion, calculate q, w, and ΔE. Cp for CO2 is 37.1 J K-1 ...In the text the equation ΔG = ΔGo + RT ln(Q) was derived for gaseous reactions where the quantities in Q were expressed in units of pressure. We also can use units of mol/ L for the quantities in Q— specifically for ...The third law of thermodynamics states that the entropy of a perfect crystal at 0 K is zero. In Appendix 4, F-(aq), OH-(aq), and S2-(aq) all have negative standard entropy values. How can S8 values be less than zero? Consider 1.0 mole of a monatomic ideal gas in a container fitted with a piston. The initial conditions are 5.0 L and P = 5.0 atm at some constant T. a. If the external pressure is suddenly changed to 2.0 atm, show that ...
