FLASHCARD QUESTION

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%.

FLASHCARD QUESTION

Front

What is the theoretical yield?

Back

The theoretical yield is the maximum amount of product that can be produced from a given amount of reactants, based on stoichiometric calculations.

5.

FLASHCARD QUESTION

Front

What is the actual yield?

Back

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