Reversible Reactions and Dynamic Equilibrium

Question 1

What is a reversible reaction

Answer 1

When the products in a reaction can react to produce the original reactants

Question 2

If a reaction is endothermic in one directon it is ____ in the opposite (reversible) directon?

Answer 2

exothermic

Question 3

Give the named example of a reversible reaction

Answer 3

hydrated copper sulfate (blue)
⇌
anhydrous copper sulfate (white) + water.

forward reaction = heated, endothermic

reverse reaction= heat is given off when water is added, exothermic

thermal decomposition of hydrated copper sulfate

Question 4

What colour is hydrated copper sulfate in the reversible reaction

it’s HYDRATED😉😉

Answer 4

blue

Question 5

What colour is anhydrous copper sulfate in the reversible reaction?

anhydrous= dehydrated/ containing no water!!

Answer 5

White

Question 6

When is equilibruim reached in a reaction?

Answer 6

When the foward and reverse reaction are taking place at the same rate

Question 7

When is the ony time that equilibrium can be reached in a reaction

Answer 7

When the reversible reaction takes place in an apparatus which prevents the escape of reactants and products
(in a closed system)
