IB DP Chemistry R2.3 L4 | What the Magnitude of K Means | Lesson Walkthrough

Interpret the magnitude of an equilibrium constant and explore how its value changes when the equation is transformed.

Predict equilibrium shifts caused by concentration, pressure and temperature changes and distinguish these from changes in K.

Explain dynamic equilibrium in a closed system and distinguish equal reaction rates from equal concentrations.

Write equilibrium constant expressions from balanced equations and use stoichiometric coefficients as powers.

Calculate equilibrium constants from composition data using careful concentration bookkeeping.

Calculate the reaction quotient and compare Q with K to predict the direction of net reaction.

Construct ICE tables and solve for equilibrium composition using exact algebraic methods.

Use and test small-K approximations, then solve mixed equilibrium-composition problems.

Connect the equilibrium constant with standard Gibbs energy and use the relationship to predict reaction position.

Explain successful collisions through energy and orientation, and use particle models to compare rates.
