WebQuestion: Question 16 (1 point) For the reaction X Z, if the plot of 1/[X] vs. t is linear: The reaction is zero order The reaction is first order The order of the reaction cannot be determined from this The reaction is second order . … WebFor a first-order reaction, a plot of the natural log of the concentration of the reactant (A) versus time (t) results in a straight line. The slope (m) represents the negative of the rate constant (k) and the y-intercept (b) represents the natural log of the initial concentration.
WebThe meaning of FIRST-ORDER REACTION is a chemical reaction in which the rate of reaction is directly proportional to the concentration of the reacting substance. WebFirst, a summary of the differential and integrated rates laws from Lectures 1 and 2 in a handy little table. In addition to the equations we have derived, note the comparison curves for first and second order integrated equations are also provided. In plot (a) note that in the first t 1/2 of 1.73 s, the concentration of A falls from 1.0M to 0.5M.
WebFor a first order reaction: ln ( [A]) = -kt + ln ( [A]0), the y variable is now ln ( [A]) and the x variable is still time. If we tried plotting ln ( [A]) versus time and get a straight line now, then it's first order. The slope will be -k and the y-intercept will be ln ( [A]0). WebFor a first order reaction, as shown in the following figure, the plot of the logrithm of [A] versus time is a straight line with k = - slope of the line. Other graphs are curved for a first order reaction. For a second order …
WebThe plot of ln [H 2 O 2] versus time is linear, indicating that the reaction may be described by a first-order rate law. According to the linear format of the first-order integrated rate law, the rate constant is given by the negative of this plot’s slope. slope = change in y change in x = Δ y Δ x = Δln [ H 2 O 2] Δ t
