Frequently Asked Questions
Is photochemical smog explained?+
Yes — the full sequence (NO2 photolysis → O atoms → ozone + organic radicals → PAN) is drawn step-by-step with the conditions for smog formation.
Do the notes cover ozone-depletion mechanism?+
Yes. The Cl-radical chain mechanism initiated by CFC photolysis is covered, with the catalytic cycle that lets one Cl atom destroy thousands of ozone molecules.
Is the BOD vs COD distinction made clear?+
Yes. BOD measures only biodegradable organic load, COD measures total chemically oxidisable matter — with the typical values for clean vs polluted water tabulated.
