What is electro chemical reaction​

Answer 1

Answer:

Electrochemical reaction, any process either caused or accompanied by the passage of an electric current and involving in most cases the transfer of electrons between two substances—one a solid and the other a liquid.

Answer 2

Electrochemistry is the study of how electrical energy is used to create non-spontaneous chemical changes and how electricity is produced from energy released during spontaneous chemical processes.

Explanation:

• Electrochemical processes create a wide range of metals, including sodium and magnesium, as well as compounds like sodium oxide and gases like chlorine and fluorine.
• Batteries and fuel cells are devices that transform chemical energy into electrical energy on a massive scale.
• The electrical work done in one second is equal to the electrical potential multiplied by the total charge passed.
• Charge must be passed reversibly if we want to get the most work out of a galvanic cell. The reversible work done by a galvanic cell is equal to the reduction in its Gibbs energy, therefore if the cell's EMF is E and the quantity of charge transmitted is nF, delta G is the reaction's Gibbs energy.
