Slow step

How can you recognize what step is slow in the reaction?

It should be given. If not given you can substitute values in to this step's rate law. When the rate law, which now includes these substituted values, matches with the overall rate law, then the rate-determining step has been found. This is assuming that every step is the slow one and finding the actual slow step by matching it to the overall rate law.

The slow step should have a rate law that is equivalent to the observed rate law.

Your slow step would be the one that determines the rate, so you can compare the rate laws of the steps to whichever rate law is experimentally determined for the complete reaction.
