Each orders' units

Postby JoseGonzalez_Lec2_2H » Wed Feb 22, 2017 9:43 pm

Can I say a reaction constant's order off its units? For example: if a reaction constant has one over seconds(s^-1) can I say solely off the units that it is first order?

Yes you can. It would be a clever way to ask a question on the quiz. based on the units, you can determine the order.

To add, k is just a constant that equates each side of the equation. So if you know the units of K, then you roughly know what each side is made up of and can determine its order that way

Depending the molar concentrations above and below in the fraction, you cancel whichever units that may remain after.
