Third order units of k

WebFeb 12, 2024 · Zero-order reactions always have rate constants that are represented by molars per unit of time. Higher order reactions, however, require the rate constant to be … where n is the reaction order. From this equation, a general formula for the units of k is obtained which is: k units = M 1-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 = M 1-3 · t-1 = M-2 · t-1 If the time is ... See more Zero-order indicates that the rate does not depend on the concentration, and therefore, the rate is equal to the concentration. rate = k[A]0 [A]0 = 1, therefore, rate = k The … See more Let’s assume it is a first-order reaction in molecule A: rate = k[A] The units for the rate are mol/L. The rate constant is equal to: k=rate[A] And now, … See more Notice how for each order, we determined the units of k by dividing the rate by molarity raised to the power of the reaction order: … See more Let’s assume it is a second-order reaction in molecule A: rate = k[A]2 k=rate[A]2 And now, add the units for the rate and concentration: k=molL×s÷(molL)2=molL×s×L2mol2=Lmol×s … See more
