← ScienceWhich consequence accelerates the rate of saponification when using concentrated NaOH?
A)Increased hydroxide nucleophilic attack✓
B)Lowered activation energy barrier
C)Catalytic micelle formation increases
D)Enhanced autoionization equilibrium shifts
💡 Explanation
Higher [NaOH] increases hydroxide ions, enhancing the **nucleophilic attack** mechanism, leading to faster ester hydrolysis because it provides more reactive species. Thus, the rate increases, rather than being affected by activation energy or forming micelles because the effect of increased concentration is direct.
