Collision Theory & Reaction Rates

These flashcards cover key concepts related to collision theory and factors affecting reaction rates.

Collision Theory

Molecules must collide with enough energy and in the correct orientation in order to react.

Activation Energy (EA)

The energy required to break bonds in order to initiate a reaction.

Successful Collision

A collision that results in a reaction due to correct orientation and sufficient energy.

Temperature's Effect on Reaction Rate

Increasing temperature increases the kinetic energy of particles, leading to more collisions and a faster reaction rate.

Concentration's Effect on Reaction Rate

Increasing concentration results in more particles per unit volume, leading to more collisions and a higher reaction rate.

Catalyst

A chemical that increases the rate of a reaction by decreasing the activation energy.

Surface Area's Effect on Reaction Rate

Increasing surface area (or decreasing particle size) leads to more collisions and a faster reaction rate.
