Quantitative Equilibrium Calculations and Le Chatelier's Principle
Students will learn how changes in conditions (concentration, temperature, pressure) can affect the position of equilibrium in a reversible reaction.
Key Questions
- Calculate equilibrium concentrations and Kc from initial concentrations and the extent of reaction, setting up and solving an ICE (Initial–Change–Equilibrium) table for a second-order system.
- Analyse whether adding an inert gas at constant volume versus constant pressure shifts the equilibrium position for a gas-phase reaction, using Kp to justify the prediction rigorously.
- Design a strategy to maximise yield in an industrial reversible reaction by systematically varying temperature, pressure, and concentration, weighing thermodynamic constraints against kinetic and economic factors.
