PROBLEM: Question: If something has a small surface area and is being mixed with something else it will react
Answer: slower

SOLUTION: Surface Area of Reactants When a solid substance is involved in a chemical reaction, only the matter at the surface of the solid is exposed to other reactants. If a solid has more surface area, more of it is exposed and able to react.

PROBLEM: Question: Ian sees an object with few colliding particles, and he compares it to another object with few colliding particles. Which is true about the objects?
Answer: the object with many colliding particles has a lower concentration of particles

SOLUTION:
At higher concentrations, particles of reactants are crowded closer together, so they are more likely to collide and react.
