Thin Layer Chromatography: Imagine that A has an Rf value of 0.85 and B has an Rf value of 0.45.?

How many spots do you expect to observe? Other pieces of info: A + B---> C; Reaction has not begun. b) Imagine the reaction has progressed and the reactants are partially converted into C. C has an Rf value of 0.60. If the TLC plate were spotted with the reaction mixture, how many spots would you observe. What might the TLC plate look like? c) How do you determine which spot corresponds to each component? d.) what does a tlc plate look like in the beginning, during,and end of reaction? Thanks you!
