Overall rate law of a reaction
WebStep two is the slow, rate-determining step, so it might seem reasonable to assume that the rate law for this step should be the overall rate law for the reaction. However, this rate law … WebSee Answer. Question: 1. Which of the following is/are true of reaction rates? The overall rate law is determined by the fastest step of a reaction. II. The presence of a catalyst will increase the number of molecules entering the transition state. III. An increase in temperature will increase the rate of a reaction. IV.
Overall rate law of a reaction
Did you know?
WebThe fact that the experimentally-determined rate law does not match the rate law derived from the overall reaction equation suggests that the reaction occurs over multiple steps. Further, the experimental rate law is second-order, suggesting that the reaction rate is determined by a step in which two NO 2 molecules react, and therefore the CO molecule … WebFurther, the sum a + b + p + q is the overall order of the reaction rate law. NOTE: there is no necessary relation between orders and stoichiometric coefficients. That is, a might differ from n a. Reaction rate constants are usually temperature dependent; the rate of a reaction usually increases as the temperature rises.
WebFeb 13, 2024 · $\begingroup$ Just because the rate law matches the stoichiometry does not mean it is an elementary reaction. Lots of multi-step mechanisms would result in the same rate law. On the other hand, if you specify that a reaction is an elementary one, you can infer the rate law from the coefficients of the reaction as written. $\endgroup$ – WebApr 11, 2024 · The rate law of a chemical reaction is an expression that provides a relationship between the rate of the reaction and the concentrations of the reactants …
WebMar 27, 2014 · If this mechanism is correct, then the rate law of the net reaction would be that of the rate-determining step: rate = k 1 [F 2][NO 2] 2 ... and relate this to the activation energy of the overall reaction. Write the rate law expression for a two-step mechanism in which the rate constants have significantly different magnitudes. WebA rate law shows how the rate of a chemical reaction depends on reactant concentration. For a reaction such as aA → products, the rate law generally has the form rate = k[A]ⁿ, …
