So let's conduct the same exact experiment. But now we keep our initial concentration of methyl acetate the same, and we double our concentration of our initial hydroxide. So let's stay at 0.1
molar and go from 0.5 molar of our hydroxide to 0.1 molar. We see that when we double our initial concentration of hydroxide, our initial rate also doubles. That means that our hydroxide is also proportional to our rate. So now with this result, we can find our rate law.
