The object of an experiment, the results from which are set out below was to determine the best settings for X1 and x2 to ensure a high yield and a low filtration time.
(a) Analyze the data and draw contour diagrams for yield and filtration time.
(b) Find the settings of x1 and x2 that give (i) the highest predicted yield and (ii) the lowest predicted filtration time.
(c) Specify one set of conditions for x1 and x2 that will simultaneously give high yield and low filtration time. At this set of conditions what field color and how much crystal growth would you expect?
