The rate constant for an isomerization r...

The rate constant for an isomerization reaction, `A rarr B` is `4.5 xx 10^(-3) min^(-1)`. If the initial concentration of `A` is `1 M`, calculate the rate of the reaction after `1 h`.

Text Solution

Verified by Experts

We know,
`Ararr B , K=4.5xx10^(-3) min^(-1)`
`[A]_(0)=1 M`
For I order reaction, `K=2.303/t"log"_(10) a/((a-x))`
at `t=60 min, (a-x)=?`
`4.5xx10^(-3)=2.303/60"log"_(10) 1/((a-x))`
`:. (a-x)=0.7634`
Thus, rate after `60` minute=`K (a-x)`
`=4.5xx10^(-3)xx0.7634=3.4354xx10^(-3)`
