Percent Yield

Front

What is percent yield?

Back

Percent yield is a measure of the efficiency of a reaction, calculated as the ratio of the actual yield to the theoretical yield, expressed as a percentage.

Front

How do you calculate percent yield?

Back

Percent yield = (Actual Yield / Theoretical Yield) × 100

Front

What is the 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 the actual yield?

Back

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

Front

Which yield is typically less than or equal to the theoretical yield?

Back

The actual yield is typically less than or equal to the theoretical yield.

Front

If the theoretical yield of a reaction is 50 grams and the actual yield is 45 grams, what is the percent yield?

Back

Percent yield = (45 g / 50 g) × 100 = 90%.

Front

What factors can affect the actual yield of a reaction?

Back

Factors include incomplete reactions, side reactions, and losses during product recovery.

Front

What is a limiting reagent?

Back

The limiting reagent is the reactant that is completely consumed first in a chemical reaction, limiting the amount of product formed.

Front

How can you determine the limiting reagent in a reaction?

Back

By calculating the amount of product each reactant can produce and identifying the one that produces the least.

Front

What is the significance of percent yield in chemistry?

Back

Percent yield indicates the efficiency of a reaction and helps chemists evaluate the success of their experiments.
