A first-order reaction is employed in the de- struction of a certain kind of microorganism. Ozone is used as the disinfectant, and the re- action is found to be dC dt = =-kC where C= concentration of microorganisms, microbes/mL k= = rate constant, 0.1 min-¹ t = time, min. The present system employs a completely mixed tank, and there is some thought of baf- fling it to create a series of completely mixed tanks. a. If the objective is to increase the percent- age microorganism destruction from 80% to 95%, how many CMF reactors are needed in series? b. We routinely kill microorganisms and think nothing of it. But do microorgan- isms have the same right to exist as larger organisms, such as whales, for example? Or as people? Should we afford moral protection to microorganisms? Can a mi- croorganism ever become an endangered species? As a part of this assignment, write a letter to the editor of your school newspaper on behalf of Microbe Col- iform, a typical microorganism who is fed up with not being given equal protec- tion and consideration within the human society, and who is demanding microbe rights. What philosophical arguments can be mounted to argue for microbe rights? Do not make this a silly letter. Consider the question seriously, because it reflects on the entire problem of environmental ethics. A first-order reaction is employed in the de- struction of a certain kind of microorganism.
