A reactant (A) forms two products : A overset(k_(1))(rarr)BActivation Energy E_(a_(1)) A overset(k_(2))(rarr)CActivation Energy E_(a_(2)) If E_(a_(1)) then k_(1) and k_(2) are related as :

Answer»

`k_(2)=k_(1)E^(E_(a_(1))//RT)`
`k_(1)=k_(2)e^(E_(a_(1))//RT)`
`k_(1)=Ak_(2)e^(E_(a_(1))//RT)`
`k_(1)=2k_(2)e^(E_(a_(2))//RT)`

Solution :( C) `k_(1) =A_(1)e^(-E_(a1)//RT)`
`k_(2) = A_(2)e^(-E_(a2)//RT)`
`(k_(2))/(k_(2))=((A_(1))/(A_(2))) e^((-E_(a1)+E_(a_(2)))/(RT)`
Now `(A_(1))/(A_(2))` = CONSTANT and `E_(a2)= 2E_(a1)`
`(k_(1))/(k_(2))=Ae^(E_(a1)//RT)`
`K_(1)= Ak_(2)e^(E_(a1)//RT)`
