Reversible Reactions: Flashcards

1
Q

How do we know if a reaction is reversible through the chemical equation?

A
  • It has a arrow going left and right if it is reverisble.

- It has a signle arrow if it is not reversible.

Q

What is a reversible reaction?

A
  • Products are able to react to reform to the original reactants.
  • Reversible reactions.
  • ## Change the direction of reversible reactions by changing the conditions.

Q

What are the energy changes like in reversible reactions?

A
  • Heat up the hydrated copper sulfate (blue) it reacts to form anhydrous copper sulfate (white).
  • Also produces water.

Points:
- Heating –> Putting energy in (endothermic forward reaction).
- Add water back–> Reaction reverses–> Energy is released (Exothermic).

Q

If a reversible reaction is exothermic in one direction what will be the other direction?

A
  • The opposite direction will be endothermic.
  • ## Same amount of energy is transferred in each case.
