Collide, Collision,  Collide, Proper Orientation and Energy

Explanation:

The basic premise of the collision theory is that particles must first collide if a reaction is to occur. Additionally, that collision  must be effective. To be effective, the particles must collide  with the proper orientation and the proper amount of energy.

A collision must occur before there i any reaction.

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

the answer is minerals.
