Revision Notes — Equilibrium
Key concepts, formulas, and definitions from Equilibrium for MHT-CET Chemistry preparation.
Key Topics to Revise
6.1 Equilibrium in Physical Processes
- Physical equilibrium exists between different phases of the same substance
- Examples: solid ⇌ liquid, liquid ⇌ gas, solid ⇌ gas
- Equilibrium can only be established in closed systems
6.2-6.3 Chemical Equilibrium and Law of Mass Action
- Chemical equilibrium involves reversible chemical reactions
- At equilibrium: rate of forward reaction = rate of backward reaction
- Law of Mass Action: For aA + bB ⇌ cC + dD
6.4-6.5 Homogeneous and Heterogeneous Equilibria
- Homogeneous equilibria: all species in same phase
- Heterogeneous equilibria: species in different phases
- For gas phase reactions: Kp = (pC)ᶜ(pD)ᵈ/(pA)ᵃ(pB)ᵇ
6.6-6.7 Applications and Thermodynamic Relations
- Reaction quotient Qc predicts reaction direction
- If Qc < Kc: reaction proceeds forward
- If Qc > Kc: reaction proceeds backward
