For a reaction `2Ararr3B,` if the rate of formation of B is `x"mol"//L,` the rate of consumption of A isA. xB. `(3x)/(2)`C. 3xD. `(2x)/(3)`

Answer» Correct Answer - D
For reaction, `2Ararr3B`
`-(1)/(2) (d[A])/(dt)=(1)/(3)(d[B])/(dt)`
`(d[B])/(dt)=xx"mol"//L`
`(d[A])/(dt)=-(2)/(3)rArr(d[B])/(dt)=-(2)/(3)x`
Hence, the rate of consumption of `A=[(-d[A])/(dt)=(2)/(3)x]`
