As you can see in the previous entrée this has been answered already over 30 years ago. In addition to the publications mentioned there are dozens of free publications on the web that you can read. Just start to GOOGLE (you should have done so before asking us)

Even though the formation of ozone from these photochemical reactions is better understood today, they are still being studied, since many of the intermediate reactions in the troposphere and stratosphere are not known. The question is one of kinetics (photolysis rate coefficient). The process is understood to be:

NO2 + sunlight --> NO + O

O + O2 --> O3

NO + O3 --> NO2 + O2

But the variation of respective concentrations of NO, NO2, and volatile organic compounds (VOC) contributes to varying concentrations of ozone in the lower troposphere.

NOx + VOC + sunlight --> O3 (and other products)

Again, these are oversimplifications with numerous intermediate reactions (e.g. free radicals, etc.) in between.
