  A reaction’s theoretical yield is the maximum amount of product expected when the limiting reagent is completely used up. In essence, the examples from Module 5 in which we calculated the amount of product formed during a reaction were determinations of theoretical yield.†. It is rare, however, for a reaction to actually produce the amount of

  3 concentration of N 2, H 2, or NH 3.Say we monitor N 2, and obtain a rate of - d[N 2] dt = x mol dm-3 s-1. Since for every mole of N 2 that reacts, we lose three moles of H 2, if we had monitored H 2 instead of N 2 we would have obtained a rate - d[H 2] dt = 3x mol dm-3 s-1.Similarly, monitoring the concentration of NH 3 would yield a rate of 2x mol dm-3 s-1.Clearly, the same reaction cannot ...

Thus a fractionation column that can attain the equivalent of three simple distillations would be said to have three theoretical plates.

  To determine the percent yield: Divide the actual yield made in the lab by the calculated theoretical amount, and multiply by 100. For a synthesis – to find the overall percent yield, multiply the individual percent yields of every step by each other (ex. 3 steps, all 30% yield – 0.30 x 0.30 x 0.30 = 0.27
