WebThe units in this table were derived using specific units for concentration (mol/L) and time (s), though any valid units for these two properties may be used – for example: M/hour, … WebIts units are mol dm-3 s-1. ... That means that that particular term disappears from the rate equation. The 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. center for body trustWebIn which case then no the units of the rate constant will be different depending on the overall order of the reaction. So a first order reaction's rate constant will indeed be using units of 1/s (or s^ (-1)) while the rate for a second order reaction will be in units of 1/ (M*s) (or s^ (-1)*M^ (-1)). center for body mind harmony

"WebFor first order reaction, R=K[A] 1 ⇒K=R[A] −1 Whereas, K and [A] are rate constant and initial concentration of reactant respectively. Therefore, Unit of rate constant =(molL −1) 1−nsec −1 For first order reaction, n=1 Unit of rate constant =sec −1 Hence the unit of rate constant for first order reaction is sec −1.
