This is not true, experimental yield is can be higher than theoretical or equal theoretical yield. If the experimental yield is greater though, that means that something went wrong in the experiment and that was most likely a contaminant. Ideally, you want to be as close to the theoretical yield as possible.
Theoretical yield is the theoretical amount of product possible to be created from particular amounts of reagent in a chemical reaction. The reaction itself, as well as the different components and complexity of steps, determine what a normal actual yield achieved will be.
There are several reasons why theoretical yield is not generally (and I would speculate never) achieved. Firstly, it assumes ideal reaction conditions, such as standard temperature and pressure, which are not generally achieved or kept constant. Secondly, other reactions between chemicals might occur, or the reverse reaction might keep all the reagents from forming products. Lastly, the process by which the reagents are worked up to the final reaction, for instance measuring or purification, might result in a loss of reagent and thus change the amount of product you could actually get.
Sources of error are inevitable in a lab scenario no matter how careful you are. Contamination, limitations of measurement, and human error are the most often-encountered errors. A theoretical yield represents the perfect world of math (stoichiometry.)
because experimental deal with what u are seing while theory is something that we are ot seing
Between theory and practice there is always a difference.
You must first calculate the theoretical yield of your product using the balanced equation. The crude yield is divided by the theoretical yield and multiplied by 100.
The percentage yield is the Actual Yield divided by the Theoretical Yield, all multiplied by 100. Percentage = [(Actual)/(Theoretical)] x 100
No, competing side reaction is a reson why the actual yield is more than the theoretical yield.
# Determine the limiting reagent; # Calculate the expected yield if the reaction goes to 100% completion. # Divide the actual yield by the expected yield and multiply by 100. The result is percentage yield.
calculating the percent yield.
Theoretical= calculated
The actual yield is less than the theoretical yield.
A yield is received after a person does the experiment. Second, they can never be same values. We can only get close to theoretical yield but never attain similar values under normal experimental conditions.
Percent yield = Actual Yield / Theoretical Yield * 100 hope that helps :)
If this is the actual yield, real amount produced, then you need the theoretical yield to find the percent yield. % yield = (actual yield / theoretical yield) x 100
Not at all. Just be consistent with the units of both actual and theoretical yield.
If actual yield is higher than theoretical yield then it means the required products contains impurities.
The percent yield is the ratio of the actual yield to the theoretical yield. A mole ratio is a conversion factor derived from the coefficient of a balanced chemical equation interpreted in terms of moles.

actual yield multiply by 100 = % yield theoretical yield
