Theoretical Yield Definition in Chemistry By Anne Marie Helmenstine, Ph.D. Why Is Actual Yield Different from Theoretical Yield? Usually, the actual yield is lower than the theoretical yield because few reactions truly proceed to completion (i.e., aren't 100% efficient) or because not all of...
The efficiency of your reaction will help you compute the actual yield of a chemical process using the actual yield formula - or you can simply use our amazing tool! Remember, that we also have a theoretical yield calculator and a percent yield calculator available for your chemistry ...
