Order of a Reaction -
The order of a reaction is determined as the sum of the powers of the concentration terms that appear in the experimental rate equation. It is an experimental quantity.

Formula: aA+bB\rightarrow cC+dD

               r=K[A]^{a}[B]^{b}

              order=(a+b)

The order has a relation with stoichiometry & is determined experimentally. It can be zero/fraction/negative/positive

So, for the given reaction order can not be determined because experimentally determined stoichiometry of powers of the concentration is not given.

Therefore, option(4) is correct
