Two Limiting Reactants

Postby 304310808 » Fri Dec 06, 2013 12:35 pm

This might be a silly question, but I just wanted to double check about something that I came across on the modules. Is it possible for an equation to have two limiting reactants? And if so, please provide an example or why it is like this?

If you're talking about 2 step reactions, there will be a limiting reagent for the first reaction and then one for the second one. You can refer to the first question on our Midterm this year

I believe that the question on the module is only referring to a single step reaction. In this case, there would only be one limiting reactant. Two limiting reactants would not be possible because if the elements in a reaction have the same quantity or amount then they will be completely used up. Neither limits the other.

Two reactants cannot limit each other. There is too little of one or the other, or they are present in the correct ratio, where they both would be used up completely and neither is limiting the other.

I'm a little confused. Let's say there are three reactants present. If two of the reactants are used up completely while the other is in excess, are there two limiting reactants? Is this possible?

It is highly unlikely that two reagents would be at the molar specific ratio to be both the limiting reagents. So there are almost never two limiting reactants.
