Limiting Reactants and Percent Yield
Mr. Andersen explains the concept of a limiting reactant (or a limiting reagent) in a chemical reaction. He also shows you how to calculate the limiting reactant and the percent yield in a chemical reaction.

GCSE Chemistry - What is a Limiting Reactant? Limiting/Excess Reactants Explained #27
Limiting and Excess Reactants Explained. Often, in chemical reactions there will be less of one reactant that the other - we call this one the limiting reactant because how much reaction can take place. Whereas the more abundant reactant...

The Rate-Limiting Step
In this video Paul Andersen explains why the slowest elementary step in a chemical reaction is the rate-limiting step. This step can be used to determine the overall rate law of the chemical reaction.

Stoichiometry
In this video Paul Andersen explains how stoichiometry can be used to quantify differences in chemical reactions. The coefficients in a balanced chemical equation express the mole proportions in that reaction. These values can be used to...

Limiting Regents and Percent Yield
Chemistry doesn't always work perfectly, silly. Molecules are left over when one thing runs out! Also we never get all of the products that we thought we might by doing the math. You gotta know about the limiting reagents and the percent...
