Slow step rate law
WebbThe slower step is used as the rate-determining step —because the rate of reaction can only go as fast as the slowest step. You would use the rate-determining step to write the … WebbRate Law Equation that relates the reaction rate with the concentration of reactants Reaction Order Power to which the concentration of a reactant is raised in the rate law Rate Constant Proportionality constant between the reaction rate and concentration of reactants What sign (+ or -) do both the rate constants and the reaction rates always have?

WebbA typical mechanism consistent with the experimental results (in which HA is the acid and X is the reactant) is Step 1: Step 2: Step 3: Derive the rate law from this mechanism. Determine the order of reaction with respect to HA. Determine how doubling the concentration of HA would affect the rate of the reaction. WebbStep 1: 2A B2A B slow Step 2: B+C DB+C D fast Overall: 2A+C D2A+C D Determine the rate law for the overall reaction, where the overall rate constant is represented as 𝑘.

Webb17 jan. 2024 · The slow step is also called the rate-determining step as it defines the rate law of the overall reaction. This should make sense! A reaction can only proceed as fast as its slowest step. Remember: The rate-determining step is the slowest step in a reaction mechanism and controls the overall rate of the reaction. http://mccord.cm.utexas.edu/courses/fall2024/ch302/Kinetics2-001.KEY.pdf
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? 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 ...
