# If the recovered yield in a reaction was 25*g, and the theoretical yield was 100*g what issues would the chemical engineers address in the synthesis?

Theoretical yield for a given mass of reactants is $100$ $g$. Recovered yield is $25$ $g$.
Do you think that the given reaction is economic? Where did the missing $75$ $g$ go? Did it all react, but were only $25$ $g$ recovered. Are there $75$ $g$ of reactant still in the reaction mixture, or are there unrecovered byproducts? How can we improve the reaction so that yields are improved?
