What must be met for reactant collisions to result in a successful product?

• The reactants must be mixed with each other in the proper proportions.

• The reactants must collide with enough energy, and be in the right positions.

• The reactants must have enough energy, and form the activated complex.

What do we call a substance that increases the rate of a reaction without being used up during the reaction?

• catalyst

• product

• reactant

True or False: The smaller the surface area of reactants equals a slower reaction speed

• True

• False
