Answer #1

10) Calculate the difference between the molar internal energy and the molar enthalpy for a perfect gas at 298.15K

For a perfect gas, we can use the formula:

H - U = RT

Where H is the molar enthalpy and U is the molar internal energy. R = 8.314 J/molK and T = 298.15K

We are looking for H - U, so just replace the values given above in the formula:

H - U = (8.314 J/molK)(298.15K)

H - U = 2478.8 J/mol

H - U = 2.479 kJ/mol

So, the correct answer is b) 2.4790 kJ/mol

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...
