H. Nitrogen gas and hydrogen gas combine to produce ammonia gas (NH3).
What volume of hydrogen gas at 25°C and 735 mm is required for the
complete reaction of 10.0g of nitrogen?

Respuesta :

Answer:

27.3 L

Explanation:

Reaction

  • N₂ (g) + 3H₂ (g) ⇒ 2NH₃ (g)
  • This is the basic reaction at STP

Solving

  • 10 g N₂ x 1 mol NH₃/28 g N₂ x 3 mol H₂/1 mole N₂
  • ⇒ 1.07 mol H₂

  • V = nRT/P [From Ideal Gas Equation]
  • V = 1.07 x 62.36 x 298 K / 735
  • V = 27.3 L
