VSEPR Theory: This theory predicts the shape of molecules based on the repulsion between electron pairs around the central atom.

Lewis Structure: This diagram shows the arrangement of electrons in a molecule or ion.

To learn these formulas, you should first understand the concept behind them and practice drawing Lewis structures and predicting the shape of molecules using VSEPR theory. Applying these formulas involves using the enthalpy formula to calculate the enthalpy change of a reaction and using Lewis structures to predict the reactivity of a molecule.

Electrochemistry is an important topic in JEE Chemistry, and it covers concepts such as oxidation-reduction reactions, galvanic cells, and electrolysis. The following are some of the essential formulas related to Electrochemistry:

$E{^ \circ }$cell = $E{^ \circ }$(cathode) - $E{^ \circ }$(anode): This formula relates the standard cell potential to the reduction potential of the cathode and the oxidation potential of the anode.

Nernst equation: This equation relates the cell potential to the concentrations of the reactants and products and the standard potential.

Faraday's laws: These laws relate the amount of substance produced or consumed during electrolysis to the amount of charge passed through the electrolyte.

## Download and Learn from State of Matter Formula PDF

In JEE mains chemistry we have some formulas for state of matter some of them are as follows:

### Ideal Gas Law:

The ideal gas law is a fundamental equation in thermodynamics, which describes the behavior of an ideal gas. The equation is as follows:

${PV = nRT}$

Where, P is the pressure, V is the volume, n is the number of moles, R is the universal gas constant, and T is the temperature.
