← ScienceWhich consequence results when catalyst active sites are exhausted?
A)Lower product formation reaction rate✓
B)Increased reactant activation energy offset
C)Higher reverse reaction initial rate
D)Changed reaction dynamic equilibrium position
💡 Explanation
Reduced active sites affect catalysis because adsorbed molecules become limited using Langmuir adsorption isotherm, therefore the product forms slower rather than reactants activation energy decreasing because the reaction route isn't altered.
