`aArarr bB` is a first order reaction with respect to A. The rate of this reaction can be determined from any of the following equations : `-(d[A])/(dt)=k_(1)[A] and (d[B])/(dt)=k_(2)[A] `. Deduce the relation between `k_(1) and k_(2)`.

Explanation

`-(1)/(a)(d[A])/(dt)=(1)/(b)(d[B])/(dt)`
Here, `-(d[A])/(dt)=k_(1)[A] and (d[B])/(dt)=k_(2)[A]`
`therefore(k_(1))/(a)[A] =(k_(1))/(b)[A] " or, "k_(1)xxb=k_(2)xxa`
