How to solve for k in a second order reaction
WebAug 12, 2024 · A second order reaction is a reaction where x + y = 2. This can happen if one reactant is consumed at a rate proportional to the square of the reactant's concentration (rate = k [A] 2) or both reactants are consumed linearly over time (rate = k [A] [B]). The units of the rate constant, k, of a second-order reaction are M -1 ·s -1. WebFeb 1, 2024 · rate of reaction r = k[A]0 = k For first order: the rate of reaction is directly proportional to the concentration of A r = k[A]1 For second order: the rate of reaction is proportional to the concentration of A squared r = k[A]2 The rate constant (k) 1. The units of k depend on the overall order of reaction. It must be worked out from the rate ...
