3 volumes of hydrogen are required to combine with one volume of nitrogen to form 2 volumes of ammonia. When 1 mole of hydrogen is allowed to react with the mole of nitrogen, the two gases?

  • A. Do not combine
  • B. Combine and both the gases are used up completely
  • C. \( 2 / 3 \) mole of nitrogen remains unreacted
  • D. Some hydrogen remains uncombined

Step-by-step solution

The reaction is N2 + 3H2 → 2NH3. Given 1 mole H2 and 1 mole N2, H2 is limiting. 1 mole H2 reacts with 1/3 mole N2, leaving 2/3 mole N2 unreacted.
