In several experiments on the kinetics of reaction A+B to Products, it is observed that i) On doubling the initial concentration of A, the rate was increased by four times and ii) On doubling the initial concentration of B, the rate was increased by two times.The correct statementis

Answer»

the reaction is first order in and second order in B
the reaction is first order in both the reactants
the rate equation is `(DX)/(DT)=k[A]^0[B]`
the over all order of the reaction is three

Solution :The rate law of the reaction `A + B to` PRODUCTS, as determined from its KINETICS is,
`(dx)/(dt) =k[A]^2[B]` So the overall order of the reaction is 2+ 1 = 3.
