The gas-phase reaction a > 3b is conducted isothermally in a cstr. when pure a is used as the feed a conversion of 80% is obtained with a residence time of 20 min. (based on feed flow rate). (a) assuming a zero order reaction, determine the expected conversion if an inert diluent was used to reduce the feed concentration to 50% of the value for pure a, keeping a 20 min. residence time. what residence time would you instead suggest? (b)repeat (a) for half order reaction.

When the earth was formed and cooled, why did nickel and iron end up in the center of the earth while basalt and granite ended up in the outer layers

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.
