Effect of conditions on Kp
Effect of conditions on Kp
Formula
Kp changes with T only
Real World
In the Haber process, raising temperature above 450 °C decreases Kp for the exothermic N₂ + 3H₂ ⇌ 2NH₃ reaction, reducing the equilibrium yield of ammonia — a real trade-off BASF engineers must manage.
Exam Focus
Distinguish clearly: pressure changes equilibrium position but not Kp; temperature changes both — examiners test this distinction directly.
