Percent Yield

Front

What is Percent Yield?

Back

Percent Yield is a measure of the efficiency of a reaction, calculated as (actual yield / theoretical yield) x 100%.

Front

What is Theoretical Yield?

Back

Theoretical Yield is the maximum amount of product that can be produced in a chemical reaction under ideal conditions.

Front

What is Actual Yield?

Back

Actual Yield is the amount of product that is actually obtained from a chemical reaction, measured in grams.

Front

How do you calculate Percent Yield?

Back

Percent Yield = (Actual Yield / Theoretical Yield) x 100%.

Front

If the theoretical yield is 100g and the actual yield is 80g, what is the percent yield?

Back

Percent Yield = (80g / 100g) x 100% = 80%.

Front

What does a percent yield of over 100% indicate?

Back

A percent yield over 100% indicates that there may have been an error in measurement or that impurities were included in the actual yield.

Front

What is the relationship between limiting reagent and percent yield?

Back

The limiting reagent determines the maximum amount of product that can be formed, thus affecting the theoretical yield and percent yield.

Front

If 50g of product is expected but only 30g is produced, what is the percent yield?

Back

Percent Yield = (30g / 50g) x 100% = 60%.

Front

What is the significance of a low percent yield?

Back

A low percent yield indicates that the reaction was not efficient, possibly due to side reactions, incomplete reactions, or loss of product.

Front

What is the difference between theoretical yield and actual yield?

Back

Theoretical yield is the calculated maximum amount of product, while actual yield is the amount obtained from the experiment.
