Limiting Reactant Chemistry Example 3

Follow the full solution, then compare it with the other examples linked below.

Example 3

medium
In a reaction A+2Bā†’C\text{A} + 2\text{B} \rightarrow \text{C}, if you have 33 mol of A and 44 mol of B, which is limiting?

Solution

  1. 1
    For 33 mol A, you need 2Ɨ3=62 \times 3 = 6 mol B. You only have 44 mol B.
  2. 2
    B is the limiting reactant. It limits the product to 42=2\frac{4}{2} = 2 mol C.

Answer

BĀ isĀ limitingĀ (producesĀ 2Ā molĀ C)\text{B is limiting (produces 2 mol C)}
Compare the available moles to the required moles using the stoichiometric ratio to identify the limiting reactant.
