# What is limiting reactant and percent yield?

Aug 9, 2016

The limiting reactant is the reactant that is consumed completely in a chemical reaction OR that produces the least number of moles of products in a chemical reaction.

#### Explanation:

Percent yield can be calculated by the formula

"Percent yield"= "actual yield"/"theoretical yield" × 100 %

THEORETICAL YIELD: The quantity of product calculated from the balanced chemical equation is called theoretical yield of reaction.

ACTUAL YIELD: The quantity of product that is actually produced in a chemical reaction is called actual yield.
