Name four factors that can affect the rate of a chemical reaction. How does the rate of a chemical reaction change in response to a change in each factor?

Question

My answer:

Four factors that can affect the rate of a chemical reaction are concentration, surface area, temperature, and catalysts.

I don't get the second part.

Answer 1

The rate of the reaction increases with increased concn, increases with increased surface area, generally increases with increased temperature, and increases with the use of a catalyst.
