Reaction Rate

Rate = k[A]^m[B]^n; units: mol L⁻¹ s⁻¹
Quick Reference
Formula / NotationRate = k[A]^m[B]^n; units: mol L⁻¹ s⁻¹
Also Known AsRate of reaction, chemical reaction rate, kinetic rate

What is Reaction Rate?

The change in concentration of a reactant or product per unit time, typically expressed in mol/L/s. Rates depend on concentration, temperature, catalysts, and surface area. The rate decreases as reactants are consumed (for most reactions) and is measured by monitoring concentration changes.

Formula & Notation

Rate = k[A]^m[B]^n; units: mol L⁻¹ s⁻¹

Other Names / Synonyms: Rate of reaction, chemical reaction rate, kinetic rate

Properties & Characteristics

Reaction rate is the change in concentration of reactants or products per unit time. It depends on concentration, temperature, pressure, and the presence of catalysts. The rate is described by a rate law derived experimentally. Rates typically increase with temperature following the Arrhenius relationship.

Uses & Applications

Reaction rate data is used to design chemical reactors and optimise production efficiency. In pharmaceutical manufacturing, controlling reaction rates ensures product quality. Environmental chemists use reaction rates to model pollutant degradation.

Safety Information

Very fast reaction rates can lead to runaway reactions, explosions, or rapid heat generation. Monitoring and controlling reaction rates is critical to chemical plant safety.

Always consult the SDS/MSDS before handling any chemical. This information is for educational purposes only.
