Reversible reactions & equilibrium
Narrated lesson · press play
Not every reaction is one-way. Some run forwards AND backwards depending on the conditions. Meet the ⇌ arrow, use hydrated copper sulfate as the classic example, learn what dynamic equilibrium means, and predict how changing conditions shifts the balance.
What you'll learn in this lesson
By the end you should be able to (NSSCO Chemistry 6.5):
- Describe that some reactions can be reversed by changing the conditions (including the effect of heat on hydrated salts, e.g. hydrated copper(II) sulfate and hydrated cobalt(II) chloride)
- Define dynamic equilibrium
- Describe that reversible reactions can reach dynamic equilibrium in a closed system
- Predict the effect of changing concentration, temperature and pressure on equilibria
