Does the size of the reactant influence the rate? I.E. is a bigger molecule consumed at a faster rate than say a hydrogen atom?

I believe only the stoichiometric coefficient of the reaction would impact the rate (ie- if 2 or 1 or 3 molecules are colliding, etc.)

I would assume that it would make it easier for the molecules to collide if they were bigger in size, so it is possible that the rate would increase, but I'm not too sure.

It's possible given that it would be able to come into contact with more at one time, but for this class I'm pretty sure just the stoichiometric coefficients matter.

Smaller particles have more surface area, which allow for the possibility of more collisions and increase the rate.

I read that if a particle (ie. solid reactant) is broken down into small bits, it leads to greater surface area and a faster reaction rate. But it doesn't affect the formed products in any way.

No, only stoichiometric coeffecients affect the rate of a reaction, not the size of the reactant molecules.
