Factors Influencing Reaction Rates in Chemistry

Enzymes

Biological catalysts that speed up digestion.

Surface area

Increased area for reactions in solid reactants.

Pressure of gases

Higher pressure increases collision frequency in gases.

Inversely proportional

Rate of reaction and time relate inversely.

Rates of reactions

Kinetics of how fast reactions occur.

Collision theory

Particles must collide for reactions to happen.

Activation energy

Minimum energy required for a reaction.

Frequency of collisions

Number of collisions per second during reactions.

Particle speed

Velocity of particles affecting collision frequency.

Concentration

Amount of particles per volume in a reaction.

Catalysts

Substances that lower activation energy for reactions.

Temperature

Higher heat increases particle speed and collisions.

Correct orientation

Proper alignment of particles for effective collisions.

Calcium carbonate formula

Reference compound for understanding reaction rates.

Success of collisions

Collisions resulting in a chemical reaction.

Methods to increase reaction rate
