For the reaction : aA+bB to Product (dx)/(dt)=k[A]^(a)[B]^(b) If concentration of A is doubled, rate becomes four times. If concentration of B is made four times, rate becomes doubled . Hence

Answer»

`-(d[A])/(DT)=-(d[B])/(dt)`
`-(d[A])/(dt)=-4(d[B])/(dt)`
`-4(d[A])/(dt)=-(d[B])/(dt)`
NONE of these
