The rate law for this reaction is of the form: Rate = k[I −]x[BrO − 3]y[H +]z. where the value of the rate constant, k ...
Witryna19 wrz 2024 · The general rate law for the reaction is given in Equation 14.3.12. We can obtain m or n directly by using a proportion of the rate laws for two experiments in which the concentration of one reactant is the same, such as Experiments 1 and 3 in Table 14.3.3. rate1 rate3 = k[A1]m[B1]n k[A3]m[B3]n. k Units of a Zero-Order Reaction. Zero-order indicates that the rate does not depend on the concentration, and therefore, the rate is equal to the concentration. rate = k [A] 0. [A] 0 = 1, therefore, rate = k. The units for the rate are mol/L, so it is the same as the rate constant: k = mol/L s or M/s or M x s-1.
