K_c = \frac{[C]^c [D]^d}{[A]^a [B]^b}
1. What does the equilibrium constant (Kc) indicate about a chemical reaction?
2. According to Le Châtelier’s principle, what happens when the temperature of an exothermic reaction is increased?
3. How does increasing pressure affect the equilibrium of a gaseous reaction?
Le Châtelier’s principle — effect?
System shifts to counteract disturbances to restore equilibrium.
Chemical equilibrium — definition?
State where reactant and product concentrations remain constant.
Kc — role?
Expresses the ratio of concentrations at equilibrium.
Chemical equilibrium — definition?
State with constant concentrations over time.
Reversible reactions — difference?
Proceed in both forward and reverse directions.
Equilibrium constant (Kc) — role?
Shows ratio of products to reactants at equilibrium.
