Webis second order in NO 2 and zero order in CO at 100 °C. What is the rate law for the reaction? Solution The reaction will have the form: rate = k[NO2]m[CO]n The reaction is second order in NO 2; thus m = 2. The reaction is zero order in CO; thus n = 0. The rate law is: rate = k[NO2]2[CO]0 = k[NO2]2 Web12 Sep 2024 · For these second-order reactions, the integrated rate law is: 1 [A] = kt + 1 [A]0 where the terms in the equation have their usual meanings as defined earlier.

The order of the reaction is … descargar flash player 8 gratisWebSo 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)). So a first order reaction and a second order reaction can have the same numerical value for their rate constants, but it's inaccurate to say that they are the same since they are using different … chrysler 200 limited 2016Web21 Feb 2024 · For first order, the units are 1/s or s^-1. For second order, the units are 1/M*s or L*mol^-1*s^-1. You will notice that there is a pattern here. Every time the order is increase by one we divide by M or mols/L. So therefore, for a third order, the units of k would be 1/M^2*s or L^2*mol^-2*s^-1.
