Difference Between Limiting Reagent/ Reactant

Postby alex_4l » Thu Oct 10, 2019 6:36 pm

I was a little confused on the difference between the limiting reagent and reactant and I figured maybe other people were as well, so I have some reminders of the differences!

Limiting Reactant: limiting amount of product that can be made. This is done by looking at the lowest amount you have in order to determine how much product can be made. The limiting reactant is completely consumed so there is none left over (smallest amount dictates how much product can be made since it holds everything else back).

Limiting Reagent: how much you need rather than how much you're going to get. This is done by picking one product from the equation to do both reactants which would give you the same answer.

Hope this helps! Feel free to add on to anything I talked about :)

It is also important to note that one must look at the lowest amount OF MOLES when determining the limiting reactant. Make sure to balance the equation first and then compare the ratio of moles of the reactants to see which reactant has less moles according to the ratio.
