I am pondering over how the rate of corrosion in metals are effected. Does E(V) of the reactions play an important part in this?
There are a number of variables which affect corrosion rates, which is somewhat related to the electric current. Applied voltage is one variable, in addition to the inherent electrochemical potential between the cathodic and anodic metals.supasupa said:I am pondering over how the rate of corrosion in metals are effected.

Corrosion is the process of deterioration or degradation of a material, usually a metal, due to chemical reactions with its environment.
The rate of corrosion can be influenced by various factors such as the type of metal, its exposure to moisture and oxygen, temperature, pH level, presence of impurities, and the chemical composition of the environment.
Corrosion can be prevented by using protective coatings, corrosion-resistant metals, alloys, and paints. Other methods include cathodic protection, which involves placing sacrificial anodes to protect the metal, and controlling the environment by reducing moisture and acidity.
The rate of corrosion for a metal depends on its electrochemical properties and how it reacts with its environment. Some metals, such as aluminum and stainless steel, have a protective oxide layer that slows down the corrosion process. Other metals, like iron, are more susceptible to corrosion because they do not form a stable oxide layer.
Corrosion can lead to structural damage, loss of material, and decreased performance of equipment or structures. It can also cause safety hazards and impact the environment through leaks or contamination of soil and water sources.
