When reacting at +0.25 V for 22.5 h, the [v(C=O)] peak intensity decreases sharply, which indicates that this voltage can significantly increase the rate of saponification reaction;
When the response is 22.5 h at .25 V, the peak strength of the v (C-O) decreases sharply, which indicates that the voltage can significantly increase the rate of the saponification reaction;
