Catalytic ammonia synthesis reaction as in Haber's process is_________________?
Correct answer: B. Exothermic
- A. Endothermic
- B. Exothermic
- C. Irreversible
- D. None of these
Explanation
The Haber reaction releases heat when nitrogen and hydrogen form ammonia, so it is exothermic. It is also reversible, but irreversible is not among the correct choices.
