A reactant (A) forms two products : A overset(k_(1))to B, Activation Energy E_(a_(1)) A overset(k_(2))to C, Activation Energy E_(a_(2)) If E_(a_(2))=2E_(a_(1)), then k_(1) and k_(2) are related as

Answer»

`k_(1)=2k_(2)e^(Ea_(2)//RT)`
`k_(2)=k_(1)e^(Ea_(1)//RT)`
`k_(2)=k_(1)e^(Ea_(2)//RT)`
`k_(1)=A" K"_(2)e^(Ea_(1)//RT)`

Solution :`k_1=A_1e^(-E_(A1)//RT), k_2=A_2e^(-E_(a2)//RT)`
`:.""k_1/k_2=A_1/A_2e^((E_(a_2)-E_(a1))//RT)=A_1/A_2e^((2E_(a_1)-E_(a_(1))))`
`(because E_(a2)=2E_(a_1))`
or `k_1=k_2Ae^(E_(a1)//RT)`
