Which is not correct about the manufacture of ammonia by Haber - Process? The break opening of the nitrogen triple bond (N = N) to form N2H2 in first step of the reaction is taken as:
Correct answer: C. Highly endothermic
- A. Very difficult step
- B. Highly unstable product
- C. Highly endothermic
- D. None of the above
Explanation
The Haber process involves the synthesis of ammonia (NH3) from nitrogen (N2) and hydrogen (H2) gases. The forward reaction is exothermic, meaning it releases heat. The breaking of the nitrogen triple bond (N≡N) to form N2H2 is not highly endothermic in this context. Instead, the entire process moves towards equilibrium and is managed to maximize ammonia production. The incorrect option is C, as the forward reaction in the Haber process is exothermic, contrary to what the term 'highly endothermic' would suggest.

About Haber's Process
Haber's process produces ammonia by reacting nitrogen with hydrogen in a reversible, exothermic equilibrium. The topic covers the iron catalyst, operating temperature and pressure, Le Chatelier's principle, the compromise between reaction rate and equilibrium yield, and the removal and recycling of ammonia and unreacted gases.
