Semi-batch reactor. consider the single liquid-phase reactiona + b -> productswhich takes place in an ideal (i. e. perfectly-mixed), semi-batch reactor. the initial volume ofliquid in the reactor is v0 and the initial concentrations of a and b in this liquid are ca0 and ba0 respectively. liquid is fed continuously (assume linear feed rate) to the reactor at a volumetric flow rate v. the concentration of a and b in this feed are caf and cbf respectively.(a) derive a design equation for this system by carrying out a material balance on "a". it isrecommended that you derive your design equation in terms of ca.(b) ultimately, we would like to determine ca as a function of time. under what conditionsis the design equation that you derived sufficient to do this? assume that the rateequation (the form of –ra) is known.

Dying the folding patterns of protein molecules can microbiologists better understand cellular processes as well as some diseases, such as alzheimer’s, that are caused by proteins that have misfolded. the folding of these complicated molecules can be simulated on computers, but it takes a lot of processor power and time for even expensive supercomputers to do this. a group of researchers at stanford university developed software that can be used to distribute the processing of data to anyone who is willing to donate time on their idle personal computers. as a result, the researchers have been able to achieve protein-folding simulations that are far better than those other computing methods have done. which statement best describes the work of these researchers? the work is not scientific because the data are not processed in one location. the work is not scientific because the simulations are not reproducible. the researchers applied creativity to solve a problem in running an experiment. the researchers used only well-established scientific techniques.
