Kr Units for Different Order Reactions

[J Medina 2I]

What units is Kr in a first order, 2nd order, and 0 order reaction?

[Victoria Zheng--2F]

The unit of K for a zero-order reaction is M/s, which is the same as the unit of rate. The unit of K for a first-order reaction is 1/s. The unit of K for a second-order1/M reaction is 1/M*s. The unit of rate is always M/s

[Chris Charton 1B]

Because rate is expressed in M/s, you have to adjust the units for k depending on the order.

0 order; units from [concentration (m/l)]^0 is removed, so k's units are M/s
1st order; units from [concentration (m/l)]^1 is present, so k's units are 1/s
2nd order units from [concentration(m/l)]^2 needs to be countered so k's units are l/m*s or 1/Ms

If the reaction was 3rd order, something like k[A]^2[B], then k's units would be l^2/m^2*s or 1/M^2*s

will we have to know third order reactions?
