The number of moles of hydrogen molecules required to produce 20 moles of ammonia through Haber’s process is :
  1. A
    10
  2. B
    20
  3. C
    30
  4. D

View written solutionFree

Correct answer: C

According to Haber's process,

N2(g) + 3H2(g) ⇌ 2NH3(g)

2 moles of NH3 uses 3 moles of H2

So, 20 moles of NH3 will use 32{3 \over 2}23​ ×\times× 20 moles of H2

= 30 moles of H2
