First Order Reaction Units The differential equation describing first order kinetics is given below: rate = − d[a] dt = k[a]1 = k[a] the "rate" is the reaction rate (in units of molar time) and k is the reaction rate coefficient (in units of 1 time). however, the units of k vary for non first order reactions. these differential equations are separable, which simplifies. In a first order reaction, the reaction rate is directly proportional to the concentration of one of the reactants. first order reactions often have the general form a → products. the differential rate for a first order reaction is as follows: rate = −Δ[a] Δt = k[a] (14.5.1) (14.5.1) rate = − Δ [a] Δ t = k [a] if the concentration of.
First Order Reaction Units From this equation, a general formula for the units of k is obtained which is: k units = m1 n · t 1. where n is the reaction order. for example, let’s say we want to determine the units of the rate constant for third order reactions. n = 3, and therefore, k units = m1 3 · t 1 = m 2 · t 1. if the time is seconds, then the units will be:. Aboutabout this video. transcript. the units of the rate constant, k, depend on the overall reaction order. the units of k for a zero order reaction are m s, the units of k for a first order reaction are 1 s, and the units of k for a second order reaction are 1 (m·s). created by yuki jung.
