Slow step rate law
Webb(a) The first step of this mechanism is rate-determining (slow). What is the rate law for this reaction? Rate = k [HBr] [O2] Rate = k [HBr]2 [O2] Rate = k [HBr] [O2]2 Rate = k [HBr]1/2 [O2] Rate = k [HBr] [O2]1/2 Rate = k [HBr]2 Rate = k [HBr]2 [O2]1/2 (b) What would the rate law be if the second step of this mechanism were rate-determining?

Example 3: Write the rate law for 2 O X 3 3 O X 2 given that the first step is fast and reversible, and the second step is slow. Step 1 (fast, reversible) O X 3 ↽ − − ⇀ k 1 k − 1 O X 2 + O Step 2 (slow) O + O X 3 → k 2 O X 2 + O X 2. The rate is determined by the slowest step.

Webb13 mars 2024 · You can do this with the pre-equilibrium approach, which Lavelle went over in class. Usually the 1st step is fast, so it will be at equilibrium by the time you get to the …
WebbA reaction that occurs in two or more elementary steps is called a multistep or complex reaction. A reaction intermediate is a chemical species that is formed in one elementary step and consumed in a subsequent step. The slowest step in a reaction mechanism is … WebbStep 1: A B + C slow Step 2: C + D E fast Overall: A + D B + E Determine the rate law for the overall reaction, where the overall rate constant is represented as 𝑘.

Webb15 mars 2024 · Below is the general equation: 2O 3 ↔ 3O 2. Under experimental conditions, scientists have determined that the rate law equation for this reaction is: Rate = k [O 3] 2 [O 2] -1. This rate law tells us some very important things about the rate and type of reaction. Here, the exponent on ozone tells us that every time the concentration of ozone ...
Webb17 mars 2024 · The two important components to look for when determining reaction mechanisms are 1) that the sum of elementary steps = overall reaction and 2) that the mechanisms must agree with the experimentally determined rate law.
