1check this out:- they say order can be negative in case of complex reactions and in 2O3→3O2

1order of a reaction is the sum of the powers of concentration terms of reactants in the rate law expression.
so if the sum of powers is negative,order will be negative though cant give an example as such because the rate law expression has to be derived experimentally.

1Negative-order reactions are rare, for example the conversion of ozone to oxygen (order −1).......................................................yes it can be arka is correct
1btw,madhu i hope complex reactions and their mechanisms arent there in jee,are they?
