question has starting materials. please answer

b. What would silica TLC plates look like when this reaction is being monitored by TLC every 15 minutes over the course of an hour (50% ethyl acetate/50% hexanes)? Please draw spots and indicate the relative locations (approximate R values), and intensities of the spots (by shading) on the TLC plate at each time point with the given % completion on the plates below. Assume 1, 2, and 3 can be visualized by a UV lamp and that compound 1 is the limiting reagent.
