NEET Chemistry Limiting Reagent MCQ Question
In a reaction between nitrogen and hydrogen to produce ammonia, which of the following statements is true regarding the limiting reagent?
If there is less hydrogen than required, hydrogen will be the limiting reagent.
Nitrogen is always the limiting reagent when producing ammonia.
Ammonia production continues until all hydrogen is consumed, regardless of nitrogen amount.
The limiting reagent cannot be determined without knowing the temperature and pressure.
Correct Answer
Detailed Explanation
When there is an insufficient amount of hydrogen compared to nitrogen for the reaction to produce ammonia, hydrogen becomes the limiting reagent, as demonstrated in the example where 4.96 × 10^3 mol of H2 was less than required for 17.86 × 10^2 mol of N2.
