Assessment Objectives

Detailed Breakdown: Equilibrium

• State the characteristics of a system in dynamic equilibrium.
• Define the reaction quotient ($Q$) and the equilibrium constant ($K_c, K_p$).
• Predict the shift in equilibrium using Le Chatelier's Principle when temperature, pressure, or concentration changes.
• Write the equilibrium law expression for a balanced reversible equation.
• Calculate unknown equilibrium concentrations using ICE tables when $K_c$ is known.
• Predict the direction of shift by comparing $Q$ to $K_c$ at a given moment.
• Relate the magnitude of $K_c$ to the extent of reaction and the stability of reactants vs products.
• Use the relationship $\Delta G = -RT \ln K_c$ to link thermodynamics and equilibrium.
• Analyze the efficiency of the Haber and Contact processes in terms of yield vs rate optimizations.
