Equation for rate law
Did you know?
WebOne method of directly measuring k, p, and q is called the method of initial rates. By measuring the initial rate (the rate near reaction time zero) for a series of reactions with varying concentrations, we can deduce to what power the rate depends on the concentration of each reagent. WebThe value of the "rate constant" k depends on how you define the rate. No matter how we define "the rate" and what we define as the stoichiometry (e.g. 2 A B or A 1 2 B or 200 A 100 B, the rates must be equal. Therefore: r A = 200 k 3 [ A] 2 = 2 k 2 [ A] 2 = k 1 [ A] 2. That is, 200 k 3 = 2 k 2 = k 1.
