NEET Formula 2026: Chemistry and Physics Important Formula Sheet PDF

Chemistry is a significant subject in NEET, and its formulae play a crucial role in solving the problems in the exam. NEET Chemistry formulae are a set of important equations, constants, and values that are required to solve problems related to different topics of Chemistry. It is essential for the NEET aspirants to have a good understanding and memorisation of the NEET Chemistry formulae to score well in the exam. 

Here are some important NEET Chemistry formulas:

1. Ideal Gas Law: $PV = nRT$

2. Boyle's Law: $PV = k$ (constant at constant temperature)

3. Charles's Law: $\dfrac{V}{T} = k$ (constant at constant pressure)

4. Gay-Lussac's Law: $\dfrac{P}{T} = k$ (constant at constant volume)

5. Henry's Law: $C = kP$ (concentration of gas in solution)

6. Rate of Reaction: $\text{Rate }= k\left[A\right]^m\left[B\right]^n$

7. pH Scale: $pH = -log[H^{+}]$

8. Acid Dissociation Constant: $K_a = \dfrac{\left[H^{+}\right]\left[A^{-}\right]}{[HA]}$

9. Base Dissociation Constant: $K_b = \dfrac{\left[OH^{-}\right]\left[B^{+}\right]}{\left[BOH\right]}$

10. Henderson-Hasselbalch Equation: $pH = pK_a + log \left(\dfrac{\left[A^{-}\right]}{\left[HA\right]}\right)$

11. Nernst Equation: $E = E^\circ - \left(\dfrac{0.0592}{n}\right)log(Q)$

12. Gibbs Free Energy: $\Delta{G} = \Delta{H} - T\Delta{S}$

13. Arrhenius Equation: $k = Ae^{\left(\dfrac{-Ea}{RT}\right)}$

14. Mole Fraction: $\text{Mole Fraction }= \dfrac{\text{Number of moles of component}}{\text{Total number of moles of all components}}$

15. Molarity: $\text{Molarity (M) } = \dfrac{\text{Number of moles of solute}}{\text{Volume of solution in liters}}$

Note that this is not an exhaustive list of all the NEET Chemistry formula sheets, but rather a selection of important ones that are frequently used in the exam. Candidates should consult their NEET Chemistry textbooks and study materials for a comprehensive list of formulas and equations.
