Which one of the following statements is true? O A catalyst alters the equilibrium constant of a reaction and is neither a product nor a reactant in the overall equation. In order for a reaction to occur, product and reactant molecules must collide with each other. The transition state is a short-lived, high energy state, intermediate between products and reactants. In reactions that are first order in one reactant and first order in another, the slow step always involves 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...
