## Question:

Use the following equation: {eq}4Fe(g) + 3O_2 (g) \to 2Fe_2O_3(s) {/eq}

If 32 moles of Fe and 27 moles of {eq}O_2 {/eq} are reacted, which is the limiting reagent?

## Limiting Reactant

The limiting reactant in a reaction is the reactant that is completely consumed first and thus limits the amount of products that can be produced. Once the limiting reactant is used up, the reaction will stop even when there are other reactants remaining.
