Question 1 · 1 mark · Difficulty 1/3

The ⇌ symbol in an equation indicates a:

  1. Reversible reaction
  2. Combustion reaction
  3. Neutralisation
  4. Precipitate
Show answer & explanation
✓ Answer: AReversible reaction
The ⇌ symbol shows the reaction can proceed in both directions (reversible).
Question 2 · 1 mark · Difficulty 2/3

A reversible reaction in a closed system reaches equilibrium when:

  1. The forward and backward reactions occur at the same rate
  2. All reactants are used up
  3. The reaction stops completely
  4. Only the forward reaction happens
Show answer & explanation
✓ Answer: AThe forward and backward reactions occur at the same rate
At equilibrium the forward and backward reactions proceed at equal rates, so the amounts of reactants and products stay constant.
