Which factor would speed up a chemical reaction? (Choose all that apply) Decreasing particle size
Increasing the temperature
Decreasing the temperature
Increasing particle size

Increasing the temperature

Increasing particle size

Explanation:

Increasing the temperature allows for particles and molecules to move faster (because there is an increase in energy) and allows for more collisions.

∴ Increasing the temperature would be an answer.

Increasing the particle size allows for more surface area and a greater chance for particles to collide with each other.

∴ Increasing particle size would be an answer.
