Lesson outcome
I can identify a reactant as an excess or limiting reactant and use that information to calculate a theoretical yield.
Show transcript
In a chemical reaction, the atoms in reactants are rearranged and are the same atoms that are in the products.
A theoretical yield is calculated using the stoichiometry of a balanced equation & relevant mathematical relationships.
The number of moles of limiting reactant available is used to calculate the theoretical yield of a reaction.
If a reactant is added excess, not all of it will react and some will be found in the final product mixture.
A limiting reactant is one that restricts the amount of product that can form from the available particles.
