Rates of Reaction and Factors Affecting Reaction Rates

These flashcards cover key concepts related to rates of reaction, including factors influencing reaction rates and the role of catalysts.

Rate of Reaction

Refers to how quickly the reactants are converted into products.

Collision Theory

Explains how the interaction of particles must occur with sufficient energy and correct orientation for a reaction to take place.

Activation Energy

The minimum energy that must be input for a chemical reaction to occur.

Surface Area

The measure of how much exposed area a solid object has; increasing it can speed up reactions.

Concentration

The amount of a substance in a given volume; increasing it can increase the rate of reaction.

Catalyst

A substance that increases the rate of a chemical reaction without being consumed in the process.

Enzyme

Biological catalysts that speed up chemical reactions in living organisms.

Temperature Effect on Reaction Rate

Increasing temperature increases the speed and kinetic energy of particles, leading to more frequent collisions.

V2O5

Vanadium oxide, used as a catalyst in the production of sulfuric acid.

Catalytic Converter

Device in vehicles that uses catalysts to convert harmful gases into less harmful emissions.

Decomposition Reaction

A reaction where a single compound breaks down into two or more products.

Measuring Reaction Rate

Determined experimentally by measuring the change of reactants or products over time.
