How does the limiting reagent differ from the excess reagent?

The limiting reagent is the one with the highest molar mass, while the excess reagent has a lower molar mass.

The limiting reagent is completely consumed, while the excess reagent remains after the reaction.

The excess reagent determines the theoretical yield, while the limiting reagent does not affect the yield.

The limiting reagent is always the reactant with the smallest initial mass, while the excess reagent has a larger initial mass.
