Instructions Consider the graph below when answering Question 8. Potential Energy Profile 80.4 points For the overall reaction: AD Consider the potential energy profile. there is a potential energy profile showing the reaction progress: Part A: How many elementary steps are there in this reaction? Part B: How many intermediates are formed? Step 1: ClO+H2OHOCl+OH Consider the reaction mechanism. Step 2: Br+HOClHOBr+Cl Step 3: OH+HOBrH2O+BrO First: Identify which substance(s) is/are an intermediate or catalyst. BACKGROUND Hint: Some of the substances may be neither an intermediate or a catalyst. Writing plausible reaction mechanisms: Second: the net reactant(s) and product(s) in the overall reaction. Sum of elementary steps MUST give the overall balanced equation for the reaction. The rate-determining step is the SLOWEST step in the sequence of steps leading to product formation. The rate-determining step should predict the same rate law for the overall reaction rate law that is determined experimentally. - Slow first step: The overall rate law is dependent only on the first step. - Fast first step: The slowest step still limits the reaction rate, but the overall rate law will still depend on the first step. When a rate-determining (SLOW) step is not the first step, the rate law for the overall reaction is not written directly from the molecularity of the first step. Net Reactant(s) Nat Drondurt(c)
