Important NEET Chemistry Formulas and Concepts to Memorize

  • Mole Concept: n=massMolar massn = \frac{mass}{Molar \ mass}n=Molar massmass​

  • Ideal Gas Equation: PV=nRTPV = nRTPV=nRT

  • Rate of Reaction: Rate=k[A]m[B]nRate = k[A]^m[B]^nRate=k[A]m[B]n

  • Equilibrium Constant: K=[products][reactants]K = \frac{[products]}{[reactants]}K=[reactants][products]​

  • Heat Capacity: q=mcΔTq = mc\Delta Tq=mcΔT

Ensure these formulas are on your fingertips for fast recall during the exam.
