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 …

Oct 13, 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 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 a very important relationship in chemistry. It is right at the heart of explaining the effect of temperature and catalysis on the rate of a chemical reaction.

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.

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 …

Arrhenius was a contented man, happy in his work and in his family life. During the First World War, he made successful efforts to release and repatriate German and Austrian scientists who had been …

Arrhenius was the first to use the principles of physical chemistry to estimate the extent to which increases in the atmospheric carbon dioxide are responsible for the Earth's increasing surface …

An Arrhenius base is a compound that increases the OH − ion concentration in aqueous solution. The reaction between an Arrhenius acid and an Arrhenius base is called neutralization and results in the …
