NEET Physical Chemistry Formulas 

Physical Chemistry is numerical-heavy and tests conceptual clarity through direct formula application. Topics like Thermodynamics, Electrochemistry, and Kinetics require precision and strong memory of standard equations. Below are NEET Physical Chemistry Formulas:

Ideal Gas Equation:  $PV=nRT$ where $P$ is pressure, $V$ is volume, $n$ is the number of moles, $R$ is the gas constant, and is the temperature.

Boyle's Law: P 1 ​ V 1 ​ = P 2 ​ V 2 ​ for a given amount of gas at a constant temperature.

Charles' Law: V 1/ T 1 ​ ​ ​ = V 2 ​ ​/ T 2 ​ for a given amount of gas at constant pressure.

Avogadro's Law: V 1/ n 1 ​ ​ ​ = V 2/ n 2 ​ ​ ​ for a given temperature and pressure.

Van der Waals Equation (for real gases): ( P + V 2 a n 2 ​ ) ( V − nb ) = n RT where $a$ and $b$ are Van der Waals constants.

Gibbs Free Energy (for a spontaneous process): $\Delta G=\Delta H-T\Delta S$ where $\Delta G$ is the change in free energy, $\Delta H$ is the change in enthalpy, $\Delta S$ is the change in entropy and $T$ is the temperature.

First Law of Thermodynamics: $\Delta U=q+w$ where $\Delta U$ is the change in internal energy, $q$ is the heat absorbed or released, and $w$ is the work done.

Rate of Reaction (for zero-order reaction): $\text{Rate}=k$

Rate of Reaction (for first-order reaction): $\text{Rate}=k[A]$ where $[A]$ is the concentration of the reactant.

NEET Organic Chemistry Formulas

Organic Chemistry focuses on molecular transformations and reaction mechanisms. Understanding general formulas and reaction strategies is important for handling typical NEET questions. Below are NEET Orgainic Chemistry formulas:

Alkanes 

Alkenes

SN1 and SN2 Reactions:

NEET Inoroganic Chemistry Formulas

Inorganic Chemistry is more factual but still includes fundamental formulas and rules. These help in understanding molecular behaviour, reactivity trends, and structural characteristics. Below are NEET Inorganic Chemistry formulas:

Degree of Unsaturation: 

Acid-Base Reactions:

Electrophilic Addition Reaction in Alkenes:

Elimination Reactions (E1 and E2):
