... that take place in this ozone layer. Scientists are finding more and more things out with time and this builds up a whole picture of the stratosphere in chemical terms and more things can then be found out. Scientists have to analyse the air by using various types of spectroscopic techniques. The reason why these work so effectively is ... of the remaining oxygen molecules, and their concentration can be measured using spectroscopic instruments at different times after the flash. An expression is then used to find the rate of reaction: Rate of reaction=k(O2)(O) K=rate constant (O2)(O)=...
