Question

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

Answer 1

Adding a catalyst

Step-by-step explanation:

A catalyst is a substance that can affect the rate of a reaction, while not changing itself. A good example of a biological catalyst, would be an enzyme.

While increasing the temperature of the reaction might increase the rate of reaction, adding a catalyst will exponentially increase the rate of reaction.

Catalysts can be used in industry, when the product is not being produced fast enough, a catalyst is added.

Answer 2

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.
