Can work be done by a galvanic cell?

This type of electrochemical cell is often called a voltaic cell after its inventor, the Italian physicist Alessandro Volta (1745–1827). 1: Electrochemical Cells. A galvanic cell (left) transforms the energy released by a spontaneous redox reaction into electrical energy that can be used to perform work.

What is the meaning of charge has to be passed reversibly?

If we want to obtain maximum work from a galvanic cell, then charge has to be passed reversibly. This explains that, the electric work has been done by the system on the surrounding for which the electrical charge supplied must be negative(i.e. charge has to be passed reversibly).

What is the potential of hydrogen electrode in contact with a solution whose pH is 10?

−0.591V .
So, the potential of hydrogen electrode in contact with a solution whose pH is 10 is −0.591V .

What is the maximum useful electrical work can be obtained at standard condition for every mole of CD consumed?

the maximum work done for the consumption of every mole of Cd=−212.2KJ.

What is the maximum electrical work?

Electrical work is the maximum work that the system can produce and so is equal to the change in free energy. Thus, anything that can be done with or to a free energy change can also be done to or with a cell potential.

How does concentration affect voltage in a galvanic cell?

In an electrochemical cell, increasing the concentration of reactants will increase the voltage difference, as you have indicated. A higher concentration of reactant allows more reactions in the forward direction so it reacts faster, and the result is observed as a higher voltage.

What is galvanic cell give the working and reaction of galvanic cell?

Galvanic cell → A galvanic cell is an electrochemical cell that converts the chemical energy of a spontaneous redox reaction into electrical energy. Working of galvanic cell → It involves a chemical reaction that makes the electric energy available.

What is happening in a galvanic cell?

Galvanic cells, also known as voltaic cells, are electrochemical cells in which spontaneous oxidation-reduction reactions produce electrical energy. The reaction may be split into its two half-reactions. Half-reactions separate the oxidation from the reduction, so each can be considered individually.

Why charge has to be passed reversibly from a galvanic cell?
