Consider the reaction nA+nB toProducts, when concentration of both reactant A and B is doubled the rate increases by eight times. However, when concentration of A is doubled keeping the concentration of B fixed the rate is doubled. The overall order of reaction is :

Answer»

`0`
`1`
`2`
`3`

Solution :Rate `(r )=K[A]^(alpha)[B]^(beta)=K[x]^(alpha)[y]^(beta)`
`r=K(2x)^(alpha)(2Y)^(beta)=2^((alpha+beta)).Kx^(alpha)y^(beta)`…….`(i)`
`2r=K(2x)^(alpha)y^(beta)=2^(alpha)Kx^(alpha)y^(beta)`…………`(II)`
`(iii)//(i) ` gives `2=2^(alpha) :.alpha=1`
`(ii)//(iii)` gives `4=2^(beta) :.beta=2`
OVERALL order `=1+2=3`
