Which change will cause the greatest increase in the rate of reaction for this chemical reaction?

8Zn (s) + S8 (s) 8ZnS (s)

adding a catalyst

increasing the temperature

increasing the surface area

increasing the concentration

The best answer to this question is adding a catalyst.

Adding a catalyst will cause the greatest increase in the rate of reaction for this chemical reaction, 8Zn (s) + S8 (s) 8ZnS (s).

---> adding a catalyst always affects the rate of a reaction.
