Since the rate … WebbQuestion: In the overall reaction that produces nitric oxide from N_2 and O_2 the slow step in the mechanism is the reaction between atomic oxygen and molecular nitrogen to produce nitric oxide and atomic nitrogen. Write out the chemical equation for the slow step and the rate law equation for it. Given that its rate constant at 800degree C is 9.7 times …
Slow step rate law
Did you know?
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 … WebbIn the case of this hypothetical reaction, if step 1 is the slow step and step 2 is the fast step of the reaction, then the overall reaction rate depends on step 1; the slow step in a …
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. Webb28K views 8 years ago Dr. Shields shows how to derive the rate law from a multi-step kinetic mechanism involving a fast equilibrium step. Intermediates are discussed, as …
Webb14 mars 2024 · Hi, The slow step is the rate determining step because it dictates how fast the reaction can go overall. For instance, if we assume the initial rates of Step 1 and Step 3 are 50 M/s and 60 M/s respectively, yet Step 2 is proceeding at 20 M/s the reaction cannot go faster than 20 M/s because the slowest step in a sense controls the other steps. WebbRate laws (sometimes called differential rate laws) or rate equations are mathematical expressions that describe the relationship between the rate of a chemical reaction and …
