"Witryna21 lut 2024 · For a zero order, the units of k are M/s, or mol*L^-1*s^-1. 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 ...
