Reversible Reactions And Equilibria
Overview
Most of the reactions you have studied so far go in one direction only: reactants turn into products and that is the end of it. But some reactions can go both ways. The products can reform the original reactants, and under the right conditions both directions happen at the same time.
In this lesson you will learn what makes a reaction reversible, explore two classic examples (ammonium chloride and hydrated copper(II) sulfate), and understand how the equilibrium symbol tells you that both forward and reverse reactions are taking place simultaneously.
Objectives
- Know that some reactions are reversible and that this is indicated by the equilibrium symbol in equations
- Describe reversible reactions such as the dehydration of hydrated copper(II) sulfate and the effect of heat on ammonium chloride
