In a chemical reaction, the limiting reactant is the one that runs out first, stopping the reaction. But how do you find it? In this video, we go step by step to determine which reactant is limiting and how to solve these problems efficiently.
🔹 When the ratio is 1:1 – You can simply compare the amounts of reactants. Whichever is smaller is the limiting reactant.
🔹 When the ratio isn’t 1:1 – A direct comparison won’t work, so we use a simple trick to adjust for different coefficients.
🔹 Dividing by the coefficient – This lets us standardize the reactant amounts, making it easy to see which one will run out first.
