← ScienceWhich consequence results when a lower catalyst concentration is used to break down hydrogen peroxide?
A)Reduced rate of decomposition reaction✓
B)Increased activation energy of decomposition
C)Equilibrium shifts toward reactants quickly
D)Catalyst is irreversibly consumed immediately
💡 Explanation
A lower catalyst concentration decreases the reaction rate via collision theory, because fewer catalyst molecules are available for interaction. Therefore, hydrogen peroxide decomposes more slowly, rather than undergoing other changes involving equilibrium shifts or catalyst consumption.
