ملخص الدرس

This lesson establishes the principles of dynamic chemical equilibrium (Rate_forward = Rate_reverse > 0) in closed reversible systems. It presents the Law of Mass Action, defining equilibrium constants K_c and K_p, and their relationship K_p = K_c (RT)^(Δn_g). It explains the exclusion of pure solids/liquids and interprets the magnitude of K as an indicator of reaction extent.

• Dynamic equilibrium: Forward rate equals reverse rate; concentrations remain constant.
• Equilibrium constant: K_c = ([C]^c [D]^d) / ([A]^a [B]^b).
• Partial pressure constant: K_p = (P_C^c P_D^d) / (P_A^a P_B^b).
• K_p and K_c relation: K_p = K_c (R T)^(Δn_g).
• Pure solids (s) and pure liquids (l) are omitted from equilibrium expressions.
• K >> 1 favors products; K
