Ozone Formation: NO2(g), is formed by chemical reactions involving N2(g) and O2(g) at the high temperatures Inside internal combustion engines in our cars. In the presence of sunlight, NO2(g) reacts with O2(g) to generate Os(s) as described by the following overall reaction: NO2(g) + O2(g) = NO(g) +...

I have a test tomorrow and really need help seeing how to do
numbers 1,2,3 and 4. If you can start with telling me what equation
to use, then solving using that equation, it would be much
appreciated.

To understand how elementary steps make up a mechanism and how the rate law for an elementary step can be determined. Very often, a reaction does not tell us the whole story. For instance, the reaction NO2(g)+CO(g)→NO(g)+CO2(g)NO2(g)+CO(g)→NO(g)+CO2(g) does not involve a collision between an NO2NO2 molecule and a COCO molecule. Based on experimental data at moderate temperatures, this reaction is thought to occur in the following two steps: NO2(g)+NO2(g)→NO3(g)+NO(g)NO2(g)+NO2(g)→NO3(g)+NO(g) NO3(g)+CO(g)→CO2(g)+NO2(g)NO3(g)+CO(g)→CO2(g)+NO2(g) Each individual step is called an elementary step. Together, these...

7. Scientists like to use data to build physical models (or mathematical models to predict how data will look). Linear trends are easiest to work with; so we often look for ways to identify linear trends in a data set.
