In the gaseous phase ammonia formation reaction (N2 + 3H2 ⇌ 2NH3), the value of the equilibrium constant depends on the_________________?
Correct answer: D. Temperature
- A. Total pressure of the system
- B. Volume of the reactor
- C. Initial concentration of N2 and H2
- D. Temperature
Explanation
For a specified reaction and standard state, the equilibrium constant is a function of temperature, as expressed through the van’t Hoff relation. Pressure, reactor volume, and initial amounts can change the equilibrium composition but not K at a fixed temperature.
