### Slow/Fast Step

Is it possible to determine what step is the slow step and what step is passed if we are only given the rate law?

### Re: Slow/Fast Step

The elementary slow step will be the one that reflects the rate law. Sometimes this is given directly in the slow step in terms of concentrations of reactants. In other cases you may have to use the pre-equilibrium method to substitute out a concentration of an intermediate.
