Q3. Standard enthalpies of formation for atomic oxygen and for
ozone are given here:
O(g), ΔfH° = 249.2 kJ mol-1.
O3(g), ΔfH° = 142.7 kJ mol-1
For each of the reactions below, evaluate the standard reaction
enthalpy (kJ mol-1) corresponding to the dissociation threshold,
and therefore calculate the wavelength (nm) and state the “colour”
of a photon with the minimum energy sufficient to achieve
dissociation.
(a) dissociation of molecular oxygen, O2(g). {numerical ans. 240
nm}
(b) dissociation of ozone, O3(g),...

What are the main chemical reactions involved in AMD
formation?
What is the “initiator reaction” and the “propagation cycle”?
Why is this cyclical nature (regeneration of Fe2+) problematic?
How do microbes play a role in these reactions?
What is “yellow boy”?
Oxidation of Fe2+ is very slow at low pH values. Why does this
reaction occur then in acidic environments?
