Svante Arrhenius

My theory was born in controversy, but truth prevails.

The temperature of the earth's surface is determined by the balance between the radiation received from the sun and the radiation emitted by the earth itself.

Any doubling of the percentage of carbonic acid in the air would raise the temperature of the earth's surface by 4°C.

The earth's temperature would be about 15°C lower if there were no carbonic acid in the atmosphere.

The absorption of heat by carbonic acid is of paramount importance for the temperature of the earth's surface.

The ocean acts as a great regulator of the carbonic acid content of the atmosphere.

The combustion of coal and other fossil fuels will lead to a considerable increase of the carbonic acid in the atmosphere.

The increase of carbonic acid in the atmosphere will, in all probability, lead to a gradual increase of the earth's temperature.

The theory of electrolytic dissociation has been confirmed by a large number of experiments.

Acids, bases, and salts, when dissolved in water, dissociate into ions.

The conductivity of electrolytic solutions is due to the movement of ions.

The degree of dissociation depends on the concentration of the solution and the nature of the electrolyte.

The properties of solutions are largely determined by the number of ions present.

The concept of ions provides a unified explanation for a wide range of phenomena in physical chemistry.

The rate of chemical reactions is influenced by temperature, concentration, and the presence of catalysts.

The Arrhenius equation describes the temperature dependence of reaction rates.

The activation energy is the minimum energy required for a chemical reaction to occur.

A small change in temperature can lead to a large change in reaction rate.

Catalysts lower the activation energy of a reaction, thereby increasing its rate.

The study of reaction kinetics provides insights into the mechanisms of chemical processes.
