← ScienceWhich consequence results when a catalyst's active site fails?
A)Increased activation energy requirement✓
B)Shifted equilibrium constant value
C)Altered reaction rate constant
D)Decreased reverse reaction rate
💡 Explanation
Increased activation energy occurs when a catalyst fails because the **catalytic mechanism** lowers the energy barrier. Therefore, higher energy input is required, rather than only affecting the equilibrium, which uses thermodynamic constants.
