rate of reactions - reversible reactions Flashcards
1
Q
what does an arrow in one direction mean? ->
A
reaction only goes forward
2
Q
⇌
A
products can react to form original reactants - equilibrium
3
Q
how can you change direction of equilibrium?
A
by changing the conditions
example: forward - heat
backwards - cool
4
Q
what does it mean if a reversible reaction is exothermic in one direction?
A
it is endothermic in the other way but same amount of energy is released both ways
5
Q
hydrated copper sulfate (blue) ⇌
A
forward: endo
backwards: exo
anhydrous copper sulfate (white) + water
6
Q
what happens to equilibrium in a sealed container?
A
sealed container stop reactants or products escaping so the forward and reverse reaction will happen at the same rate
