Factors Affecting Reaction Rate

Vocabulary flashcards on factors affecting reaction rate based on lecture notes.

Temperature

Higher temperature increases reaction rate by increasing kinetic energy and collisions between particles.

Concentration

Higher concentration increases reaction rate because more particles in solution lead to more collisions.

Surface Area

Smaller particle size (greater surface area) increases reaction rate.

Catalyst

Speeds up reaction by lowering activation energy; it is not a reactant or product.

Pressure

Higher pressure increases reaction rate for gases only by reducing volume and increasing particle collisions. Liquids and solids are negligibly affected.
