56 ~g of nitrogen and 8 ~g of hydrogen gas are heated in a closed vessel. At equilibrium 34 ~g of ammonia are present. The equilibrium number of moles of nitrogen, hydrogen and ammonia are respectively

Options

  1. A1,1,2
  2. B2,1,2
  3. C1,2,2
  4. D2,2,1

Correct answer

A. 1,1,2

Step-by-step solution

Mass of N₂ left =56-28=28 g Moles of N ₂ left = 28 28 =1 mole Mass of H ₂ left =8-6=2 ~g Moles of H ₂ left = 2 2 =1 mole Moles of ammonia = 34 17 =2 moles
