LR – How To

To find the Limiting reactant in a chemical reaction:

  • Pick a reactant and assume it is the LR.

  • Calculate the amount of the other reactant needed to use up all of the LR.

  • Compare the amount needed to the amount available, for the second reactant. (given in the problem.)

    • If you have enough of it (more available than needed) then it is the XS reactant, and you guessed right: The first reactant is the LR

    • If you don’t have enough of it (more needed than you are given) then you guessed wrong: the second reactant is the LR and the first is in XS.

  • Determine the LR of the reaction when given 1.22g O2 and 1.05g H2.
