If 3A rarr 2B, then the rate of reaction...

If `3A rarr 2B`, then the rate of reaction of `+ (dB)/(d t)` is equal to

A

`-(3)/(2)(d[A])/(dt)`

B

`-(2)/(3)(d[A])/(dt)`

C

`-(1)/(3)(d[A])/(dt)`

D

`+2(d[A])/(dt)`

Text Solution

Verified by Experts

The correct Answer is:
B

`3Ararr2B`, Rate `=-(1)/(3)(d[A])/(dt)=(1)/(2)(d[B])/(dt)`
`:. +(d[B])/(dt)=-(2)/(3)(d[A])/(dt)`
