When do you know if you have to change a rate law into a different for using other elementary reactions? I dont understand why they changed it here. Their goal was to express it in terms of reactants and products of the overall reaction but OH- isn't in the overall reaction

Hi Alicia Lin 2F! To answer your question, the overall rate law is determined by looking at the slowest step in the mechanism because the slowest step dictates how fast the reaction progresses. To clarify, the goal of the rate law is not to express it in terms of reactants and products but to express it in a way that shows what species affect the overall rate of the reaction. I hope this helps!
