Faraday’s law is a fundamental relationship which comes from Maxwell’s equations. It serves as a succinct summary of the ways a voltage (or emf) may be generated by a changing magnetic environment.

What is the value of the equilibrium constant for the cell reaction if n = 1 ? What is the value of the equilibrium constant for the cell reaction if n = 2? What is the value of the equilibrium.

The reaction is said to be spontaneous when the cell potential is greater than zero. The Gibbs free energy is the thermodynamic potential that can be used to calculate the maximum of reversible work.

The Gibbs free energy is inversely related to the standard reduction potential. If the flow of electrons in a redox reaction is occurring spontaneously, then the Gibbs free energy change will be.

Suppose you have a fairly big negative value of ΔG° = -60.0 kJ mol-1. The first thing you have to do is remember to convert it into J by multiplying by 1000, giving -60000 J mol -1. And let’s suppose that we are interested in the equilibrium constant for the reaction at 100°C – which is 373 K.

The ampere is defined as the constant current which, if maintained in two straight. This amount of charge, equal to about 96 485 coulombs, became known as Faraday's constant. This is equivalent to exactly 3.6 kilojoule (kJ) of energy.

Gibbs free energy equation is helpful in determining the value of equilibrium constant which is denoted by symbol "K". If the value of K is greater than 1, then change in Gibbs free energy will be.

final means that the value cannot be changed after initialization, that’s what makes it a constant.static means that instead of having space allocated for the field in each object, only one instance is created for the class. So, static final means only one instance of the variable no matter how many objects are created and the value of that variable can never change.
