Question

(a) 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 fast step has more effect on the overall reaction rate than the rate of a slow step. Solid catalysts do not affect reaction rates. The rate of a reaction is the same as the rate constant of the reaction. The higher the rate of a reaction the longer it takes to reach completion.
