Reversible reactions and equilibrium

Reversible Reactions and how are they presented (⇌)

In some chemical reactions, the products of the reaction can react together to produce the original reactants. These reactions are called reversible reactions

They can be represented in the following way:

A + B ⇌ C + D

What does this symbol mean ⇌ 😒

Reversible reactions…The arrows point both ways meaning the forward reaction is one that goes right the backwards reaction is the one that left

Energy changes in reversible reactions

If a reaction is exothermic in one direction, it will be endothermic in the other direction.

The equilibrium position can be changed by changing the reaction conditions through:

• changing the pressure

• changing the concentration

• changing the temperature
