The number of moles of hydrogen molecules required to produce 20 moles of ammonia through Haber’s process is:

Step-by-step solution

Haber’s process N 2 g + 3 H 2 g ⇌ 2 N H 3 g According to the reaction, 2 moles of ammonia are produced from 3 moles of H 2 i.e., 1 mole of ammonia is produced from 3 2 moles of H 2 Thus, 20 moles of ammonia = 3 2 × 20 = 30 moles of H 2 Hence, 30 moles is the correct option.
