) Select all of the correct statements about reaction rates from the choices below.

The lower the rate of a reaction the longer it takes to reach completion. The slowest step in a reaction is called the rate-determining step. Catalysts increase reaction rates. The rate of a reaction is the same as the rate constant of the reaction. Fast reactions can be slowed down by lowering the temperature. Reaction rate constants decrease with increasing temperature. The higher the rate of a reaction the longer it takes to reach completion.
