Hi, I'm trying to learn how to use the Arrhenius equation and I
am very confused, can someone help? Thank you!
The activation energy for the gas phase
decomposition of cyclobutane is
262 kJ/mol.
(CH2)42
C2H4
The rate constant for this reaction is
2.16×10-4 s-1 at
711 K. What is the rate constant at
749 K?
Use the Arrhenius equation to determine
Ea.

This is a Lewis structure example on my Chemestry book. But I
am very confused about the number of valence electrons in Iodine on
this specific structure: in general we try to achieve the octet
rule, but on this structure Iodine have 4 lone pairs and 4 single
bond. Since each single bond equals to 2 electrons, doesn't Iodine
have way too many electrons?
thank you
