Question

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

1) The lower the rate of a reaction the longer it takes to reach completion.

2) Catalysts increase reaction rates.

3) Reactions involving very unstable combinations of chemicals have small rate constants.

4) Reaction rates increase as concentrations of homogeneous catalysts increase.

5) A balanced chemical reaction is necessary to relate the rate of disappearance of a reactant to the rate of appearance of a product.

6) Solid catalysts increase reaction rates as their surface areas increase.

7) Reactions involving very unstable combinations of chemicals have large rate constants.
