Question

Explain how chemical energy is converted into electrical energy using galvanic cell.

Answer 1

A Galvanic cell converts Chemical energy into electrical energy , by using spontaneous chemical reactions that takes place at thd electrodes. Each galvanic cell has its own characteristic voltage ( defined as the energy release per electron transfer from one electrode to other ). A simple galvanic cell will consist only an electrolyte and two different electrodes. ( Galvanic cells can also be made by connecting two half-cells , each with its own electrode and electrolyte ,by an ion-transporting "bridge", usually a salt bridge these cells r more complex .) The electrodes typically are two metals , which naturally have differnt reaction potentials relative to the electrolyte . This causes electrons of one of the electrodes to preferentially enter the solution at one electrode and other electrons to leave the solution at the outer electrode. This generates an electric current across the electrolyte ( where the charge carriers are the mobile ionic species ) ,which will drive electric current through a wire that makes an exterior connection to each of the electrodes. Both galvanic cells and electrolytic cells can use electrodes of different metals but also can use the same metal for electrodes. A rechargeable battery such as AA NiMH cell or a single cell of a lead-acid battery, acts as a galvanic cell when discharging ( Converting chemical energy to electrical energy ) , and an electrolytic cell when being charged ( Converting electrical energy to chemical energy ).

Answer 2

Answer:

Explanation:

In galvanic cell, chemical energy is converted into electrical enaert due to spontaneous movement of electrons
