Witryna-The rate law relates the rate of reaction to the concentrations of the reactants. Which of the following options correctly interpret the rate law rate = k [H2] [NO]2? -The reaction is second order with respect to NO. -If [NO] is doubled while [H2] remains the same, the reaction will occur 4 times faster. Witryna12 lut 2024 · The half-life is 96 seconds. Since this is a zero-order reaction, the half-life is dependent on the concentration. In this instance, the half-life is decreased when … Witryna16 lut 2016 · The reason for this is probably because when the reaction is 2nd order, that means that if the initial concentration decrease by 1/2, then the rate decreases … inconsistency\u0027s 2a

Reaction Order and Rate Laws Flashcards Quizlet

WitrynaThe order of reaction determines the relationship between the rate of reaction and the concentration of reactants or products. It is the power to which a concentration is raised in the rate law equation. For example, for the reaction xA + yB ---> products, the rate law equation will be as follows: Rate = k [A]^a . [B]^b. WitrynaTo determine the reaction order, the concentration of the second reactant is held constant, while the concentration of the first reactant is varied. ... The rate constant … inconsistency\u0027s 22WitrynaA 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. inconsistency\u0027s 28

"WitrynaWhile 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. " - Is second order dependent on concentration

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. Witryna2 lut 2024 · For each reaction, give the units of the rate constant, give the reaction order with respect to each reactant, give the overall reaction order, and predict what happens to the reaction rate when the concentration of the first species in each chemical …
