Question

Which of the following conditions is favourable for the production of ammonia by Haber's process?

• A. High concentration of reactants
• B. Low temperature and high pressure
• C. Continuous removal of ammonia
• D. All of these

Answer 1

The correct option is D All of these

The Haber's process have equilibrium reaction as

$N_2\left(g\right)+3H_2\left(g\right)\rightleftharpoons 2N{H}_3\left(g\right)+\Delta$

according to the Le chatelier's principle if any changes happen in any component then equilibrium will move that direction where the effect of that change neutralize. This is exothermic reaction so low temperature gives more product and due to having low number of atom in product side so high pressure give more product.
If we remove $N{H}_3$ then the equilibrium will shift toward product so due to this all options are right.
