(i) What are the two types of rate laws? (i) What do these two laws convey/tell you about a reaction (i) How are rate laws determined? (ii) What is the overall reaction order of a reaction, and how is determined? The reaction between bromate ions and bromide ions in acidic aqueous solution is given by the equation BrO_3^-(aq) + 5Br^-(aq) + 6H^+(aq) rightarrow 3Br_2(l) + 3H_2 O(l), Table 12.5gives the results from four experiments. Using these data, determine the orders for all three reactants, the overall reaction order, and the value of the rate constant. (i) What are the three types of reaction rate laws learned in Chapter 12? How are these rate laws different? What are the equations that govern these rate laws? (ii) What are the three types of reactions learned in Chapter 12? (iii) What is the rate determining step of a reaction mechanism? (iv) What does the 1/2 life of a reactant mean? Explain what it actually means and be specific. (v) How can you tell the difference among 0^th, 1^st and 2^nd order rate laws from their graphs? A first order reaction is 55% complete at the end of 35 minutes, what is the value of k?
