50 POINTS!! Explain why the size of solid particles and the temperature of reaction affects the reaction rate according to the collision theory in other words explain why a reaction speed up or slow down based on interactions between reactive molecules when temperature of the reaction or size of solid reacting particles changed

Increasing the surface area of a reactant increases the frequency of collisions and increases the reaction rate. Several smaller particles have more surface area than one large particle. The more surface area that is available for particles to collide, the faster the reaction will occur.Feb 22, 2021

Explanation:

Please mark me brainliest I would appreciate it.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
