The excess reactant remains after the reaction is over while the limiting reactant does not remain after the reaction is over.
What is limiting reactant?
The question is incomplete but I will try to help you as much as possible. The limiting reactant is the reactant that is used up in the reaction. It does not remain at the end of the reaction.
The reactant in excess is not used up in the reaction hence it remains after the reaction must have been completed.
