Negative overall order

Postby Rida Ismail 2E » Wed Mar 11, 2020 2:58 pm

Does anyone understand how an overall order can be negative and if so can you please explain it to me?

I think that an order can be negative if as you increase the concentration of a particular reactant, the overall rate of reaction decreases.

Can the whole reaction have a negative overall order or only certain steps?

I think it is rare, but if you increase the concentration of certain reactants, then the overall reaction rate will decrease.

I found an example of the conversion of ozone to oxygen here: https://www.quora.com/What-are-negative-order-reactions-And-what-are-the-examples

Like first vs second order? Negative as in less than a zero order? What would that be called and can you give an example if you found a problem with it?
