Theoretical Yield

Limiting Reactants The limiting reactant is the reactant present in the smallest stoichiometric amount In other words, it’s the reactant you’ll run out of first (in this case, the H2)

Limiting Reactants In the example below, the O2 would be the excess reactant

Theoretical Yield The theoretical yield is the amount of product that can be made In other words it’s the amount of product possible as calculated through the stoichiometry problem This is different from the actual yield, the amount one actually produces and measures

Stoichiometric Calculations

Percent Yield Actual Yield Theoretical Yield Percent Yield = x 100 A comparison of the amount actually obtained to the amount it was possible to make Actual Yield Theoretical Yield Percent Yield = x 100
