Lesson Plan: Reversible and Irreversible Reactions Chemistry

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to define reversibility in chemical reactions and identify examples of reversible and irreversible processes.

Objectives

Students will be able to

  • distinguish between reversible and irreversible reactions and suggest conditions which reverse these reactions,
  • give examples of processes and reactions and classify them as reversible or irreversible in terms of the products reacting to form the original reactants,
  • use the symbol in reversible equations,
  • explain the exothermic and endothermic nature of reversible reactions in terms of making and breaking bonds.

Prerequisites

Students should already be familiar with

  • exothermic and endothermic reactions,
  • thermal decomposition reactions,
  • writing balanced symbol equations including state symbols.

Exclusions

Students will not cover

  • the reversibility of acid–base indicators, which is not examined beyond simplified examples such as HInd(red)H+Ind(blue)+,
  • examples of static equilibria.
