If `3A rarr 2B`, then the rate of reaction of `+ (dB)/(d t)` is equal toA. `-(3)/(2)(d[A])/(dt)`B. `-(2)/(3)(d[A])/(dt)`C. `-(1)/(3) (d[A])/(dt)`D. `+2(d[A])/(dt)`

Answer» Correct Answer - B
For reaction
`3A to 2B`
`rate =-(1)/(3) (d[A])/(dt)`[ Rate of disappearance ]
`=+(1)/(2)(d[B])/(dt)`[ rate of appearance ]
`therefore + (d[B])/(dt) =-(2)/(3) (d[A])/(dt)`
