Worked practice questions

At equilibrium, the rates of the forward and reverse reactions are:

  1. The same
  2. The double
  3. The triple
  4. The reverse
Show answer and solution

Correct answer: A. The same

1. Equilibrium is a dynamic state, not a stopped one. 2. It is reached when the rates of the forward and reverse reactions become equal. 3. So the correct answer is the same. _Source: syllabus Chemistry, Ch 7 'Equilibrium'_

In a saturated sugar solution, the rate of dissolution equals the rate of:

  1. Carbonisation
  2. Crystallisation
  3. Condensation
  4. Chlorination
Show answer and solution

Correct answer: B. Crystallisation

1. A saturated solution holds a dynamic equilibrium. 2. The rate of dissolution of sugar equals the rate of crystallisation of sugar. 3. So the correct answer is crystallisation. _Source: syllabus Chemistry, Ch 7 'Equilibrium'_

An equilibrium in which reactants and products are in different phases is:

  1. Heterogeneous
  2. Homogeneous
  3. Homologous
  4. Hydrogenous
Show answer and solution

Correct answer: A. Heterogeneous

1. Phases matter when writing the equilibrium expression. 2. An equilibrium spread over more than one phase is called heterogeneous equilibrium. 3. So the correct answer is heterogeneous. _Source: syllabus Chemistry, Ch 7 'Equilibrium'_
