Hey there,
I was wondering if someone could help me with the calculations in the following question. Specifically the "alternate calibration method" where you don't use the calibration curve. I haven't been formally taught this yet and the textbook explanation is a bit confusing so any help would be greatly appreciated
EDIT: I also have another question - Why does afternoon peak hour traffic have much less effect on city ozone concentrations than the morning peak?
From my textbook, I seem to be under the impression that the ozone concentration is higher in the afternoon because over the day, the NO
x which are initially emitted by car exhausts in the morning peak, are oxidised and then photodissociated into free radical which then react with O
2. Am I missing a step where the ozone just randomly disappears because that seems to be the only missing piece that would allow me to properly explain what the question implies.
