Negative Order

[BenJohnson1H]

Would a negative order indicate that the reactant also participates in some type of reverse reaction?

[Matthew Mar 1J]

I think a negative order indicates that a reactant is involved in a reaction, but actually slows the reaction rate as its concentration increases. I think one example of a reactant is H+, because in some reactions it's involved in, a higher H+ concentration makes the solution more acidic which could slow the overall reaction. Another example is O2 in ozone production which is O2 + O -> O3, because O2 is the product of the other reactant, so when O2 is in higher concentrations, there is generally less O available for the ozone reaction.

Negative integer: A negative order indicates that the concentration of that species INVERSELY affects the rate of a reaction.
So, yes, if a species has a negative order, then it participates in a reverse reaction, thereby leading to a decrease in the reaction rate(slowing it down).

The negative order means that the rate is being decreased instead of the normal increasing rate (positive order).

[Jack Hewitt 2H]

A negative order signifies that the concentration of the reactant inversely affects the reaction rate.
