What is the difference between percent yield and theoretical yield?

[KristySpra]

I’m learning about chemical reactions and need help understanding what theoretical yield and percent yield mean, and how to calculate them. Can someone explain with examples?

Theoretical yield is the maximum amount of product that could form from given reactants, calculated using stoichiometry and assuming perfect reaction conditions. Percent yield measures the efficiency of a reaction by comparing the actual yield obtained experimentally to the theoretical yield, expressed as a percentage.

The theoretical yield is the maximum amount of product that can be produced from a chemical reaction based on stoichiometric calculations, assuming perfect conditions with no losses. The percent yield, on the other hand, measures how efficient the reaction actually was by comparing the actual yield obtained in the lab to the theoretical yield. It shows how close the experiment came to the ideal outcome.

Theoretical yield is the maximum amount of product that could be formed in a reaction based on stoichiometric calculations, assuming perfect conditions.
Percent yield shows how efficient the reaction actually was by comparing the actual yield to the theoretical yield using:
Percent Yield = (Actual Yield ÷ Theoretical Yield) × 100.
In short, theoretical yield is predicted; percent yield measures real-world efficiency.

Theoretical yield is the max product you should get from a reaction, while percent yield shows how much you actually got compared to that. For example, if theory says 10 g and you get 8 g, your percent yield is 80%.

 

[Salvatore_Damon]

The percent yield indicates how much product you actually obtained in comparison to the theoretical yield, whereas the theoretical yield is the maximum amount of product that should be formed based on the chemical equation. To put it briefly, percent yield gauges the reaction's actual efficiency, while theoretical yield is the computed ideal amount.

 

[Robert Willian]

Theoretical yield represents the utmost quantity of product that could be obtained from the reaction when everything goes perfectly. This value is computed through stoichiometric calculations. Percent yield signifies the real quantity of product which is measured in an experiment, thus goes through the theoretical yield calculation and is expressed in percentage to indicate the effectiveness of the reaction.

The theoretical yield is the maximum amount of product you can get from a chemical reaction, based on stoichiometry and assuming everything reacts perfectly. The percent yield tells you how much product you actually obtained compared to the theoretical yield, expressed as a percentage. You calculate it using:

Percent yield = (Actual yield ÷ Theoretical yield) × 100%

For example, if a reaction could theoretically produce 10 grams of salt, but you only collected 8 grams, the percent yield would be:
(8 ÷ 10) × 100% = 80%.

It basically shows how efficient your reaction was.
