Production of Ammonia by Haber's process is a _.
Correct answer: B. Exothermic reaction
- A. Endothermic reaction
- B. Exothermic reaction
- C. Irreversible reaction
- D. Redox reaction
Explanation
An exothermic reaction is a chemical reaction that releases heat to its surroundings, resulting in an increase in temperature. In the Haber process, the reaction between nitrogen and hydrogen gases to produce ammonia is exothermic. This means that heat is released during the reaction, making it suitable for industrial-scale production.

About Thermochemistry and Energetics of Chemical Reactions
Thermochemistry measures energy changes in chemical reactions and distinguishes exothermic from endothermic processes. Work covers systems, surroundings and state functions, internal energy, the first law of thermodynamics, enthalpy and Hess's law, including the sign conventions used when heat enters or leaves a system.
