A slightly bruised apple will rot extensively in about 2.0 days at room temperature (26.C). If it is kept in the refrigerator at 1.5 C, the same extent of rotting takes about 17 days. What is the activation energy from the rotting reaction? ...................... J/mol fyi( 5.9 J/mol was marked as wrong)
Homework Answers
Using the equation,
ln(k1/k2) = Ea/R(1/T2-1/T1)
where,
Ea = activation energy
k1 = 2
k2 = 17
T1 = 299 K
T2 = 274.5 K
R = 8.314 J/K.mol
Feed values,
ln(2/17) = Ea/8.314[1/299-1.274.5]
Ea = 59603.43 J/mol

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...
