In physical chemistry, the Arrhenius equation is a formula for the temperature dependence of reaction rates.

Feb 14, 2024 · The exponential term in the Arrhenius equation implies that the rate constant of a reaction increases exponentially when the activation energy decreases. Because the rate of a …

Dec 26, 2025 · Arrhenius equation, mathematical expression that describes the effect of temperature on the velocity of a chemical reaction, the basis of all expressions used for calculating reaction-rate …

In 1903 Svante August Arrhenius (1859–1927) received the Nobel Prize in Chemistry for his electrolytic theory of dissociation, which states that molecules of acids, bases, and salts dissociate into ions …

Jul 23, 2025 · The Arrhenius equation establishes a link between a chemical reaction's rate constant and absolute temperature, incorporating the A factor, or pre-exponential factor.

What is the Arrhenius Equation? The Arrhenius equation shows the relationship between k (rate constant), activation energy, temperature and collisions of reactant particles (with correct orientation).

In this tutorial, you will learn what the Arrhenius equation is, how to use the equation to determine the activation energy or rate constant of a reaction, and how to derive it.

The Arrhenius equation is one of the most important equations in physical chemistry. It describes the relationship between the reaction rate and the temperature for many chemical reactions.

The Arrhenius equation is a formula that describes the relationship between the rate constant (k) of a chemical reaction, the absolute temperature (T), and the reaction's activation energy (Ea).

This constant is applicable in contexts involving speed, energy, or velocity. Understanding the Arrhenius equation allows chemists to predict how changes in temperature can influence reaction rates, which …
