Acrylonitrile is the starting material used in the manufacture of acrylic fibers (U. S. annual production capacity is more than 2 million pounds). Three industrial processes for the production of acrylonitrile are given below. Using data from Appendix 4, calculate ΔSo, ΔHo, and ΔGo for each process. For part a, assume that T = 25oC; for part b, T = 70oC; and for part c, T = 700oC. Assume that ΔHo and ΔSo do not depend on temperature.
Answer to relevant QuestionsConsider the reaction 2POCl3(g) → 2PCl3(g) + O2(g) a. Calculate ΔGo for this reaction. The ΔGof values for POCl3(g) and PCl3(g) are –502 kJ/ mol and –270. kJ/ mol, respectively. b. Is this reaction spontaneous under ...Hydrogen cyanide is produced industrially by the following exothermic reaction: Is the high temperature needed for thermodynamic or for kinetic reasons? One of the reactions that destroys ozone in the upper atmosphere is NO(g) + O3(g) ⇌ NO2(g) + O2(g) Using data from Appendix 4, calculate ΔGo and K (at 298 K) for this reaction. Consider the following reaction at 298 K: 2SO2(g) + O2(g) → 2SO3(g) An equilibrium mixture contains O2(g) and SO3(g) at partial pressures of 0.50 atm and 2.0 atm, respectively. Using data from Appendix 4, determine the ...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.
