For a reaction `1/2 A rarr 2B` rate of disappearance of A is related to the rate of appearance of B by the expression

A

`-(d[A])/(d t) = (1)/(2)(d[B])/(d t)`

B

`-(d[A])/(d t) = (1)/(4)(d[B])/(d t)`

C

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

D

`-(d[A])/(d t) = 4(d[B])/(d t)`

Text Solution

Verified by Experts

For the reaction `(1)/(2) A rarr 2B`, the instantaneous rates are
`(dx)/(d t) = (-2d[A])/(d t) = +(d[B])/(2 dt), (dx)/(d t) = (-d[A])/(d t) = (1)/(4)(d[B])/(d t)`
