Hints

A reactant (A) forms two products :

$A \overset{k_{1}}{\to} B, Activation Energy {Ea}_{1}$
$A \overset{k_{2}}{\to} C, Activation Energy {Ea}_{2}$

If Ea₂ = 2 Ea₁, then k₁ and k₂ are related as:

1.	$k_{2} = k_{1} e^{{Ea}_{1} / RT}$	2.	$k_{2} = k_{1} e^{{Ea}_{2} / RT}$
3.	$k_{1} = k_{2} e^{{Ea}_{1} / R T}$	4.	$k_{1} = 2 k_{2} e^{{Ea}_{2} / KT}$
