The equation N2(g) + 3H2(g) ⇋ 2NH3(g) represents:
Correct answer: B. Haber's process
- A. Contact process
- B. Haber's process
- C. Solvay process
- D. Avogadro's Law
Explanation
The Haber process combines nitrogen from the air with hydrogen derived mainly from natural gas (methane) into ammonia. The reaction is reversible and the production of ammonia is exothermic. with ΔH=−92.4kJ/mol. Thus the equation in the question suits the above definition: N2(g) + 3H2(g) ⇋ 2NH3(g)

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.
