Identifying limiting reactants in industrial processes can be tricky. Here are a couple of reasons why:

• Variability in Reactant Quality: Sometimes, impurities in the materials can cause problems.

• Complex Reactions: When there are many steps in a reaction, it makes the math more complicated.

For example, when we make ammonia using the reaction ($\text{N}_2 + 3\text{H}_2 \rightarrow 2\text{NH}_3$), it's really important to measure the reactants correctly. If we make a mistake, it can waste materials and raise costs.

Solutions:

• We can use advanced techniques to analyze the materials better.

• Making sure our equipment is regularly checked and adjusted can help avoid these problems.
