In the reaction A +2B rarr C +2O the ini...

In the reaction `A +2B rarr C +2O` the initial rate `(-d[A])/(dt)` at `t=0`was found to the `2.6 xx 10^(-2) "M sec"^(-1)`. What is the value of `(-d[B])/(dt)` at `t=0` in `ms^(-1)` ?

A

`2.6 xx 10^(-2)`

B

`5.2 xx 10^(-2)`

C

`1.0 xx 10^(-1)`

D

`6.5 xx 10^(-3)`

Text Solution

Verified by Experts

`-(d[A])/(dt)=-1/2(d[B])/(dt)`
Hence `-(d[B])/(dt)=2 xx (-d[A])/(dt)`
`=2xx2.6xx 10^(-2)M sec^(-1)`
`= 5.2 xx 10^(-2)M sec^(-1)`
