unit nine : limiting and excess reactants

limiting reactant

reactant that runs out first during the reaction, determining the amount of product formed.

excess reactant

reactant that is left over after the reaction, going unused because the limiting reactant stopped the reaction.

theoretical yield

how much product we can create, depending on the limiting reactant.

actual yield

the amount of product actually created.

percent yield

the difference between theoretical and actual yield.

percent yield formula

% = actual/theoretical(100)
