determining order

Postby azirenorfleet3B » Sun Mar 04, 2018 11:17 am

when determining the order of a reactant can the value ever be 1/2 or would we round to the nearest whole number if we do not calculate a whole number?

Yes, you can have an order of 1/2. For example, if going from experiment 1 to 2 your concentration halves (say it goes from 10 to 5) and then you see from experiment 1 to 2 the rate goes down by a fourth (say from 100 to 25) then your order would be 1/2 in this case.

What would our units be for a reaction that is half order?

The units for the rate is always M/s, but the k value changes depending on the order.
