How is cell potential related to the free energy change? State meaning of each term used.

The free energy change DeltaG = 0 , when

Distinguish between electric potential and electric potential energy and state the relation between them.

When the total cell emf of the voltaic cell is greater than zero, which of the following is true about the reaction quotient Q and free energy change DeltaG for the cell reaction?

The correct relationship between free energy change in a reaction and the corresponding equilibrium constant K_(c) is:

How is electric field at a point related to potential gradient?

Gibbs Helmholtz equation relates the enthalpy, entropy and free energy change of the process at constant pressure and temperature as DeltaG=DeltaH-TDeltaS " (at constant P, T)" In General the magnitude of DeltaH does not change much with the change in temperature but the terms TDeltaS changes appreciably. Hence in some process spontaneity is very much dependent on temperature and such processes are generally known as entropy driven process. When CaCO_(3) is heated to a high temperature it decomposes into CaO and CO_(2) , however it is quite stable at room temperature. It can be explained by the fact that
