Reaction Kinetics

Question 1

What is the effect of using crushed particles rather than cubes on rate of reaction?

Answer 1

Increases the surface area to volume ratio meaning there is a large area for more successful collisions and it takes less time to break down completely.

Question 2

What is the effect of increasing concentration on rate of reaction?

Answer 2

More particles occupy the same volume meaning particles are more likely to collide with each other successfully to react because there are more than less free space to move into
