Problem 1 The gas phase pyrolysis of acetaldehyde CH3CHO- take place according to the following sequence...
Nitrogen pentoxide reacts with nitric oxide in the gas phase according to the stoichiometric equation N_2 O_5 + NO rightarrow 3NO_2 The following mechanism has been proposed. N_2 O_5 NO_2 + NO_3 fast NO + NO_3 2NO_2 slow Assume that the steady-state approximation can be applied to NO_3 and derive an equation for the rate of production of NO_2.
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...
