The rate law is an equation that relates the reaction rate with concentrations or pressures of reactants and constant parameters.

Rate Equation: This is the mathematical representation of a rate law, showing the relationship between reaction rate and concentration of reactants. Itโs like specific instructions in our cookie recipe โ e.g., โMix 2 cups flour with 1 cup sugarโ.
In multi-step reactions, this is slowest step that determines overall reaction speed. Itโs like waiting for dough to chill in fridge โ no matter how fast we mix ingredients, we canโt proceed until dough has chilled.
This formulates relation between concentration of reactants and time; it helps predict amounts at any given point during reaction. Itโs like knowing exactly when our cookies will be perfectly baked based on oven temperature and initial dough amount.
