A reactant (A) forms two products: A xrightarrowk1 B, Activation Energy Ea1 A xrightarrowk2 C, Activation Energy Ea2 If Ea2 = 2 Ea1, then k1 and k2 are related as : (A) k2 = k1eEa1 /RT (B) k2 = k1eEa2 /RT (C) k1 = Ak2eEa1 /RT (D) k1 = 2k2eEa2 /RT

k1 = A1 e-Ea1 /RT k2 = A2 e-Ea2 /RT (k1/k2) = (A1/A2)e(Ea2- Ea1 ) /RT k1 = A1 × eEa1 /RT

Q. A reactant (A) forms two products :
$A k_{1} B,$ Activation Energy $E a_{1}$
$A k_{2} C,$ Activation Energy $E a_{2}$
If $E a_{2} = 2 E a_{1}$ , then $k_{1}$ and $k_{2}$ are related as :

$k_{2} = k_{1} e^{E a_{1} / RT}$

$k_{2} = k_{1} e^{E a_{2} / RT}$

$k_{1} = A k_{2} e^{E a_{1} / RT}$

$k_{1} = 2 k_{2} e^{E a_{2} / RT}$

$k_{1} = A_{1} e^{- E a_{1} / RT}$
$k_{2} = A_{2} e^{- E a_{2} / RT}$
$\frac{k _{1}}{k _{2}} = \frac{A _{1}}{A _{2}} e^{(E_{a_{2}} - E_{a_{1}}) / RT}$
$k_{1} = A_{1} \times e^{E a_{1} / RT}$

Q. A reactant (A) forms two products : Ak1​​B, Activation Energy Ea1​ Ak2​​C, Activation Energy Ea2​ If Ea2​=2Ea1​, then k1​ and k2​ are related as :

k2​=k1​eEa1​/RT

k2​=k1​eEa2​/RT

k1​=Ak2​eEa1​/RT

k1​=2k2​eEa2​/RT

k1​=A1​e−Ea1​/RT k2​=A2​e−Ea2​/RT k2​k1​​=A2​A1​​e(Ea2​​−Ea1​​)/RT k1​=A1​×eEa1​/RT
