As we learnt in

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.

- wherein

Formula: aA+bB\rightarrow cC+dD

               r=K[A]^{a}[B]^{b}

              order=(a+b)

  \therefore     Order has relation with stoichiometry & is determined experimentally. It can be zero/fraction/negative/positive

 

 for reaction A+2B\rightarrow C

Rate = k\left [ A \right ]\left [ B \right ]^{2}}

order =1+2=3
