WitrynaThe reaction orders in a rate law describe the mathematical dependence of the rate on reactant concentrations. Referring to the generic rate law above, the reaction is m order with respect to A and n order with respect to B. For example, if m = 1 and n = 2, the reaction is first order in A and second order in B. Witrynaa. The rate of second order reactions is dependent on concentration. b. The rate of a first order reaction is dependent on concentraion. c. The half life of a second order …

Dependence of Reaction Rate on Concentration of …

WitrynaIf the reaction rate is dependent on the concentration of the reactant: then the relationship is curvilinear, as it is dependent on the changing amount of reactant Rate Law Equation Rate = k [A]^m [B]ⁿ (True/False) Reaction rates may be almost instantaneous or may be billions of year long. True Zero order WitrynaA pseudo second order reaction is a reaction for which the kinetics appear to be second order even though they are something else. Consider a third order reaction with the rate law rate = k [A]² [B]. If B is in very large excess, the concentration of B will change very little as A gets used up. [B] is almost a constant. former ffbi agent charles marlerWitrynaWhile still a second order reaction mechanistically, the reaction is kinetically first order as the concentration of the nucleophile–the solvent molecule, is effectively constant during the reaction. This type of reaction is often called a pseudo first order reaction. former file sharing service with green logo
