I am unsure of how we use the steady state approach for reaction mechanisms. Can someone please explain step by step how to use this approach?

We don't have to worry about the steady state approach in this class!
We'll rather be focusing on the pre-equilibrium approach.

The steady state approach is something we don't need to know for this test but is still a very relevant kinetics concept. It is an approach where you measure the rate of the reaction within a very, very small time frame: the moment the reaction starts, you take a quick snapshot of the atoms in reaction and measure the rate of reaction that way. Like the pre-equilibrium approach, you assume that the observed differential rate is the maximum experimental differential rate. Chemical engineers have developed technology using laser pulses to measure very precise rates in very small timeframes. Very cool question!
