What are three ways the rate of a chemical reaction can be changed

The temperature - warmer debris circulate swifter and collide greater oftentimes with greater ability.

2. The rigidity - debris in gases squeezed at the same time will collide greater oftentimes.

3. concentration of any reactants in answer.

4. floor section of any good reactants (powders have a larger entire floor section)

5. The presence of a catalyst. (catalysts decrease the activation ability)
