For the reaction, `2A + B rarr 3C + D`, which of the following does not express the reaction rate

A

`(d[D])/(d t)`

B

`(-d[A])/(2d t)`

C

`-(d[C])/(3d t)`

D

`-(d[B])/(d t)`

Text Solution

Verified by Experts

The correct Answer is:
C
`2A + B rarr 3C + D`
`:. r_("reaction") = (1)/(2) xx (-(dA)/(d t)) = -(dB)/(d t)`
`= (1)/(3) xx (+ (dC)/(d t)) = (1)/(1) xx (+(dD)/(d t))`
`:. r_("reaction") ne (d(C ))/(3d t)`
