← ScienceWhich outcome occurs when increasing temperature in Haber-Bosch process (N₂ + 3H₂ ⇌ 2NH₃, exothermic)?
A)Decreased ammonia yield due to equilibrium shift✓
B)Increased ammonia yield due to favorable enthalpy
C)Unaffected ammonia yield as rate constants equalize
D)Equilibrium shifts to reactants causing runaway cooling
💡 Explanation
When temperature increases in an exothermic reaction at equilibrium, Le Chatelier's principle dictates that the equilibrium shifts to counteract the change by favoring the endothermic, reverse reaction. Therefore, ammonia yield decreases because the equilibrium shifts to favor reactants, N₂ and H₂, instead of an increase due to temperature.
