Haber's process operates at 450°C, if it is carried out at 250°C
Correct answer: D. Rate or formation will be very slow
- A. No ammonia will form.
- B. % of NH3 will be low
- C. Catalyst would be of no use
- D. Rate or formation will be very slow
Explanation
Lower temperature slows down reaction kinetics significantly, so even though equilibrium favors NH3 at lower T, the reaction rate is very slow.

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.
