Question

Define electromotive force with example?Give the labeled for born harber cycle for the formation of NaCl crystal?​

Answer 1

In one definition, the lattice energy is the energy required to break apart an ionic solid and convert its component atoms into gaseous ions. This definition causes the value for the lattice energy to always be positive, since this will always be an endothermic reaction

Answer 2

Answer:

Electromotive force, abbreviation E or emf, energy per unit electric charge that is imparted by an energy source, such as an electric generator or a battery. Energy is converted from one form to another in the generator or battery as the device does work on the electric charge being transferred within itself

Formula

E=\frac{W}{Q}

E = electromotive force

W = work done

Q = charge
