Zeroth order: ([A0]/2k) First order: (ln(2)/k) Second order: (1/k[A0]) So the zeroth and second order require us to know the rate constant and the initial concentration, while the first order only requires the rate constant. Hope that helps.

WebSolution: Examining the data given reveals that the time for the concentration to decrease by half is 2.16 × 10 4 seconds, regardless of how much H 2 O 2 remains. From this, we can deduce that it is a first-order reaction and that t ½ = 2.16 × 10 4 s. After determining the half-life, it can be used to find k: k = = 3.21 x 10 -5 s -1. WebThe half-life of a reaction depends on the reaction order. First order reaction: For a first order reaction the half-life depends only on the rate constant: Thus, the half-life of a first order reaction remains constant throughout the reaction, even though the concentration of the reactant is decreasing.

WebFeb 12, 2024 · Half-Life in a Pseudo-1st Order reaction Half-life refers to the time required to decrease the concentration of a reactant by half, so we must solve for t. Here, [B] will be the reactant in excess, and its concentration will stay constant. [A]o is the initial concentration of A; thus the half-life concentration of A is 0.5[A]o.
