let us define the term. The first term is limiting re agent, so the reaction that is completely consumed in the reaction is called as limiting regent. It determines the amount of product formed in a chemical reaction so consumed completely on there's called us exists re agent. The reactant CE, other than the limiting reactions are called US Access reactor. They are left in the reaction even after the completion, so left in reaction reaction are excellent. What shouldn't be. The amount of product formed in the reaction is the domain by limiting the agent. So a moment off product formed bye, limiting Regent. So because it is completely consumed in a reaction on no more products can be formed using the other reactions it is limiting. Regent See in any balanced reaction, the combining ratio are molecules on more racial. Different molecules have different masses that are molar masses, so comparing initial mass off the reactor will not give the comparison enough number off molecules or moves. Thus, the choice off limiting the actor should be based on the initial mole, not on the initial mass
