Hey there!
For SN1 mechanism; the activation barrier is the C-I bond energy which is broken in the first step of the reaction.
The activation barrier is : 56 kcal/ mol = 5.6 kcal/ mole ( nearest 0.1)
The diatomic molecule H2 has an extremely low boiling point because only weak Vander waals forces are present between the atoms of hydrogen molecule. This weak inter-molecular forces are easily broken when heat is apply resulting in low boiling point.
Answer:
it's the third one
Explanation:
in the first one oxygen molecules aren't balanced
the second ok me oxygen isnt balanced
and the fourth one hydrogen isn't balanced
hope it helps ;)
The answer is B but iam not sure about the answer
