In a zero order reaction 20
WebThe meaning of ZERO-ORDER REACTION is a chemical reaction in which the rate of reaction is constant and independent of the concentration of the reacting substances. WebNov 15, 2024 · A) The equation for a zero-order reaction is the following: [A] = -kt + [A₀] Where: [A] = concentrationo f reactant A at time t. [A₀] = initial concentration of reactant A. t = time. k = rate constant. We know that at t = 155 s, [A] = 8.00 × 10⁻² M and at t = 355 s [A] = 3.00 × 10⁻² M. Then: 8.00 × 10⁻² M = -k (155 s) + [A₀]

WebThe integrated rate law for the first-order reaction A → products is ln [A]_t = -kt + ln [A]_0. Because this equation has the form y = mx + b, a plot of the natural log of [A] as a function of time yields a straight line. The rate constant for the reaction can be determined from the slope of the line, which is equal to -k. Created by Jay. Sort by:
WebMany enzyme-catalyzed reactions are zero order, provided that the reactant concentration is much greater than the enzyme concentration which controls the rate, so that the enzyme is saturated. For example, the biological oxidation of ethanol to acetaldehyde by the enzyme liver alcohol dehydrogenase (LADH) is zero order in ethanol.
