First order rate constant calculator
WebAug 17, 2024 · The first-order representation is convenient because the rate is summarized with a single parameter (the rate constant, k ), and the rate of transformation is independent of the initial concentration. The half-life, t 1/2 =ln (2)/ k, indicates the time required to reduce the concentration by 50% from any concentration point in time. WebFor first-order reactions, the rate constant is expressed in s 1 (reciprocal seconds). The units of the rate constant can be determined using the following expression: Units of k = M (1-n) .s -1 (where ‘n’ is the order of …

WebThe Rate Constant Calculator works by using the Reaction Rate formula and manipulating it to calculate the rate constant k of the chemical reaction. For instance, the rate of the … WebBecause the reaction is first order with respect to CH 3 Br, the kinetics would appear to be first order with a new "pseudo-first order rate constant", k'. The value of this rate constant would depend on the value of the overall rate constant, k, and the initial (fixed) concentration of OH -.
WebLet's try a simple problem: A first order reaction has a rate constant of 1.00 s -1. What is the half life of the reaction? Since the reaction is first order we need to use the equation: t 1/2 = ln2/k t 1/2 = ln2/ (1.00 s -1) = 0.6931 s Now let's try a harder problem: The half-life of N 2 O 5 in the first-order decomposition @ 25°C is 4.03×10 4 s.
