← ScienceWhich change results when iron promotes Haber-Bosch equilibrium?
A)Reduced activation energy requirements✓
B)Increased equilibrium constant value
C)Enhanced product thermal stability
D)Elevated reactant gas-phase pressure
💡 Explanation
The iron catalyst accelerates reaching reaction equilibrium via collision theory, decreasing the necessary activation energy for both directions because it stabilizes transition states. Therefore, the equilibrium shifts faster, rather than changing its intrinsic equilibrium constant which depends on thermodynamics.
