Assume you have a single-phase binary alloy with a composition of NA = 0.87. Also assume that the free energy of pure A is 34,000 J/mole and that the free energy of pure B is 21,500 J/mole. Assume the temperature is 1200 K.
- a. Calculate the free energy of one mole of the alloy assuming the activity of the A component is 0.83 and the activity of the B component is 0.11.
- b. Calculate the free energy of a mole of the alloy if it forms an ideal solution.
- c. Calculate the driving force for mixing of the non-ideal alloy in part (a).

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
