← ScienceWhich outcome occurs in a Haber-Bosch reactor when the ammonia removal rate decreases?
A)Reduced catalyst surface area
B)Increase in the equilibrium constant
C)Increase in reverse reaction rate✓
D)Faster hydrogen depletion
💡 Explanation
When ammonia removal decreases, the product concentration increases, thus the reverse reaction rate accelerates because chemical equilibrium shifts to relieve the stress via Le Chatelier's principle, producing more reactants. Therefore the reverse reaction rate increases, rather than altered surface area, equilibrium constant, or faster hydrogen depletion, scenarios which are independent of product concentration.
