For reaction Mixture 1 the student found that 75 seconds were necessary. On dividing equation 5 for reaction mixture1 by reaction mixture 3, as well as after cancelling out the common terms (k', terms in (I-) and (H+)), she got the equation
13.3/25 =(0.0040/0.0080)^n = (1/2)^n.
a. Recognizing that 13.3/25 is about equal to 1/2, she acquired an approximate value for n. Define what is that value?
b. Define by taking logarithms of both sides of the equation, she got an exact value for n, state what is that value?
While the orders of reactions are often integers, she reported her estimated value as the order of the reaction with respect to BrO3-.
