Manufacturing of Ammonia by the Haber's process is an?
Correct answer: B. Exothermic reaction
- A. Endothermic reaction
- B. Exothermic reaction
- C. Irreversible
- D. Slow
Explanation
The manufacturing of ammonia by the Haber's process is an exothermic reaction. The Haber's process is a well-known industrial method for the synthesis of ammonia (NH3) from nitrogen (N2) and hydrogen (H2) gases. The balanced chemical equation for the reaction is: N2 + 3H2 ⇌ 2NH3 In this reaction, nitrogen and hydrogen gases react to produce ammonia gas. The forward reaction (from left to right) is exothermic, meaning it releases heat to the surroundings. As a result, the reaction is favored at lower temperatures. The Haber's process is carried out at high pressure and moderate temperature to achieve a good yield of ammonia while considering both the reaction rate and the equilibrium position. By removing the heat generated in the exothermic reaction, the process can be made more efficient and productive.

About Chemical Equilibrium
Reversible reactions reach dynamic equilibrium when forward and reverse rates become equal, and Le Chatelier's principle predicts the effect of changing concentration, pressure or temperature. The chapter also covers solubility product, the common ion effect, buffer action and the conditions used in Haber's process, with equilibrium shifts distinguished from changes in the equilibrium constant.
