Reversible reactions and dynamic equilibrium exam tips

Exam tips

• Count Gaseous Molecules

  Use when analyzing equilibrium equations, carefully count the number of gaseous molecules on both sides.

  This keeps your answer aligned with The effect of pressure changes on equilibrium (HT only) and the approved Chemistry 8462 objective to (HT only) Count gaseous molecules on each side of an equilibrium equation.

• Practice with Examples

  Use work through various equilibrium equations to practice counting gaseous molecules and predicting the effects of pressure changes.

  This keeps your answer aligned with The effect of pressure changes on equilibrium (HT only) and the approved Chemistry 8462 objective to (HT only) Count gaseous molecules on each side of an equilibrium equation.

• Understand Gas Mole Counts

  Use when analyzing equilibrium reactions, always count the number of gaseous molecules on both sides of the equation.

  This keeps your answer aligned with The effect of pressure changes on equilibrium (HT only) and the approved Chemistry 8462 objective to (HT only) Predict that pressure has no effect on equilibrium position when both sides have the same number of gas molecules.

• Recognize Pressure Effects

  Use remember that if the number of gas molecules is the same on both sides of the equilibrium equation, changes in pressure will not affect the position of equilibrium.

  This keeps your answer aligned with The effect of pressure changes on equilibrium (HT only) and the approved Chemistry 8462 objective to (HT only) Predict that pressure has no effect on equilibrium position when both sides have the same number of gas molecules.

• Understand Pressure Effects

  Use make sure to analyze how changes in pressure affect the yield of products in equilibrium reactions.

  This keeps your answer aligned with The effect of pressure changes on equilibrium (HT only) and the approved Chemistry 8462 objective to (HT only) Evaluate pressure choices for equilibrium reactions from yield, rate and operating cost information.

• Consider Economic Factors

  Use when evaluating pressure choices, always include considerations of operating costs alongside yield and rate.

  This keeps your answer aligned with The effect of pressure changes on equilibrium (HT only) and the approved Chemistry 8462 objective to (HT only) Evaluate pressure choices for equilibrium reactions from yield, rate and operating cost information.
