Correct answer: D. 2

A B Initial concentration Rate of reaction array ll 2 10⁻³ M & 2.40 10⁻⁴ Ms ⁻¹ 1 10⁻³ M & 0.60 10⁻⁴ Ms ⁻¹ array rate of reaction r=k[A]^x where x= order of reaction hence aligned & 2.40 10⁻⁴=k [2 10⁻³ ]^x & 0.60 10⁻⁴=k [1 10⁻³ ]^x aligned on dividing eqn.(i) from eqn. (ii) we get 4=(2)^x x=2 i.e. order of reaction =2
