The rate of a chemical reaction is NOT affected by which of the following:

The rate of a reaction increases as temperature__________________.

Products will form faster if____________

A ______________ is a substance that increases the rate of a reaction without being used up during the reaction.

Catalysts permit reactions to proceed along a ___________energy path.

Smaller particle size allows for a _________ surface area to be exposed for the reaction.

The ___________ the surface area of the reactants, the faster the reaction rate.

Increasing the temperature will increase the kinetic energy of particles, therefore increasing the collisions between particles.

Usually lowering the temperature will slow down a reaction.

Increasing the concentration of the reactants will slow down the reaction.
