WebMay 10, 2024 · We begin with the notion that the slow step is the rate-determining step. From that, the initial form of the rate law is: #r(t) = k_2[C][D]# where #k_2# is the rate constant for the forward second step. However, #C# is not a reactant (but is an intermediate), and as such, this is not an appropriate rate law yet. Instead, we should … WebSep 28, 2015 · Determine the numerical value of the rate constant k with appropriate units. The units for the rate of a reaction are mol/L/s. The units for k are whatever is needed so that substituting into the rate law expression affords the appropriate units for the rate. In …
