5.3 Theoretical, Actual, and Percent Yield

Front

What is the theoretical yield?

Back

The theoretical yield is the maximum amount of product that can be produced in a chemical reaction under ideal conditions.

Front

How do you calculate percent yield?

Back

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

Front

What is the actual yield?

Back

The actual yield is the amount of product that is actually obtained from a chemical reaction.

Front

If the theoretical yield is 100g and the actual yield is 90g, what is the percent yield?

Back

Percent yield = (90g / 100g) x 100% = 90%.

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 product.

Front

What is the significance of percent yield in chemistry?

Back

Percent yield helps to assess the efficiency of a reaction and can indicate how well the reaction conditions were optimized.

Front

Calculate the percent yield if the theoretical yield is 50g and the actual yield is 45g.

Back

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

Front

What is the relationship between theoretical yield and stoichiometry?

Back

Theoretical yield is calculated based on stoichiometric ratios derived from balanced chemical equations.

Front

If 10g of reactant produces 8g of product, what is the percent yield?

Back

Percent yield = (8g / 10g) x 100% = 80%.

Front

What is the formula for calculating theoretical yield from a balanced equation?

Back

Theoretical yield = (moles of limiting reactant) x (molar mass of product).
