Can a reaction have more than one limiting reactant and why or why not? I feel like if the reactants are in the same phsyical state than it is possible. If someone can clairfy, that would be gretaly appreciated.
I think it can have more than one limiting reactant but the mole ratio has to be the same between them and the quantities used have to have to match that mole ratio, so that both are used up simultaneously. But i'm pretty sure that this is a very hypothetical situation and is not seen in chemical reactions often, if ever. I could be wrong though.
I believe that it's not possible because thinking logically, if there were two limiting reactants, they would have the exact same molar ratio. If this were true, then neither reactant would limit the other - they would both be completely consumed in the reaction.
Technically, a limiting reactant is the reactant that is completely consumed during the reaction. If there are three reactants and two of the three are totally consumed, it would make sense for them both to be limiting reactants, while the third is i n excess. I could be wrong, but that is my interpretation of the information.
Theoretically, if there are exact moles of each reactant and they are both consumed exactly, there are 2 limiting reactants (or you can also say there are no limiting reactants). However, this is almost impossible to achieve, so there is almost always a limiting reactant. In problems and tests it will be clear that we want you to find the limiting reactant.
Yea, when I took the online module that had this question, the correct answer was no (there cannot be more than one limiting reactant). This makes sense because if there were two reactants with the same mole ratio, then neither one would limit the other since they were both consumed completely in the reaction.
