Factorial Design of Experiments (K Owens comments)

I think a Norm Abram "rule for wikiposting" should be "think twice, post once". I neglected the fact that there are 4 different reagents (not one) and that if amounts of the reagents change then the ratios (excess) of one reagent over another are varied that way (the experimental factors are not independent). I'll work on this again and repost.
