Equilibrium (HT)

Revise Equilibrium (HT) in Rates of Reaction for GCSE Chemistry with 23 exam-style questions and 18 flashcards. This is a high-frequency exam topic, so students should expect to explain it clearly under timed conditions.

Sample Flashcards

What does 'dynamic equilibrium' mean?
Forward and backward reactions happen at the same rate, so concentrations stay constant
What conditions are needed for equilibrium?
A closed system (nothing can escape) and a reversible reaction

Exam questions for Equilibrium (HT)

At dynamic equilibrium, which of the following is true?

  • A. The rate of the forward reaction equals the rate of the reverse reaction
  • B. The concentrations of reactants and products are always equal
  • C. The forward reaction stops and only the reverse reaction continues
  • D. All chemical reactions have stopped
