Reversible reaction Flashcards
⇌
This is a reversible reaction.
→
The reaction happens in only one direction.
By changing the conditions…
we can change the direction of the reversible reaction.
What is formed when hydrated copper sulfate is heated?
Anhydrous copper sulfate and water.
What is the colour of hydrated copper sulfate?
Blue
What is the colour of anhydrous copper sulfate?
White
A forward reaction of hydrated copper sulfate is…
endothermic and requires heat. The reversible reaction is started by mixing anhydrous copper sulfate and water. This releases heat, so it is an exothermic reaction.
If the reversible reaction is exothermic in one direction…
it is endothermic in the opposite direction.
Always, the same amount of…
energy is transferred in both directions.
Sealed container
Stops any reactants or products from escaping.
Equilibrium
In a sealed container, at some point, the forward and the reverse reaction will take place at exactly the same rate.
