Haber's process N 2( g )+3 H 2( g ) leftharpoons NH 3( g ) 20 moles need to be produced 2 moles of NH 3 arrow 3 moles of H 2 Hence 20 moles of NH 3 arrow (3 × 20/2)=30 moles of H 2

Haber's process
$N_{2} (g) + 3 H_{2} (g) ⇌ N H_{3} (g)$
20 moles need to be produced
2 moles of $N H_{3} \to 3$ moles of $H_{2}$
Hence 20 moles of $N H_{3} \to \frac{3 \times 20}{2} = 30$ moles of $H_{2}$

Haber's process N2​(g)+3H2​(g)⇌NH3​(g) 20 moles need to be produced 2 moles of NH3​→3 moles of H2​ Hence 20 moles of NH3​→23×20​=30 moles of H2​
