First Order Reactions (Chemical Kinetics) - Units, Example, FAQs

WebA first-order reaction is a reaction where the rate is dependent on the concentration of only one reactant. Because of this, it is also called an unimolecular reaction. The units of … WebA few specific examples are shown below to further illustrate this concept. The rate law: rate = k[H2O2] describes a reaction that is first order in hydrogen peroxide and first order overall. The rate law: rate = k[C4H6]2 describes a reaction that is second order in C 4 H 6 and second order overall. The rate law: rate = k[H+][OH−] WebFirst-Order Reactions Integration of the rate law for a simple first-order reaction (rate = k [ A ]) results in an equation describing how the reactant concentration varies with time: [ A] t = [ A] 0 e − k t where [ A] t is the concentration of A at any time t, [ A] 0 is the initial concentration of A, and k is the first-order rate constant. thepurgatory.com

WebMar 12, 2024 · When a partial order is negative, the overall order is usually considered as undefined, so in above example, the reaction is not described as first order even though the sum of the partial orders is 2 + (-1) = 1, because the rate equation is more complicated than that of a first-order reaction. Top. Brandon Fujii 1K WebThe overall order of the reaction is found by adding up the individual orders. For example, if the reaction is first order with respect to both A and B (a = 1 and b = 1), the overall order is 2. We call this an overall second order reaction. Some examples
