Reversible Reactions

Question 1

How do we know the reaction is reversible ?

Answer 1

The arrow points both ways

Question 2

What are reversible reactions ?

Answer 2

Reactions were the products can react to form the reactants

Question 3

If we heat something form products than the forward reaction is ?
How would we reverse the reaction

Answer 3

Endothermic because it requires energy in the form of heat

The reactants will get hot because it’s an exothermic reaction to reverse it

Question 4

If a reversible reaction is exothermic in one direction it is … in the opposite direction ?

Answer 4

Endothermic
Same amount of energy will be transferred in each case tho

Question 5

What does hydrated copper suflate form when heated ?

Answer 5

Anhydrous copper sulfate ( white solid)
And water Vapor

Question 6

What will a sealed container do ?

Answer 6

Stop any reactants or products from escaping
This means at some point the forward and reverse reactions take place at the same rate

Question 7

What is equilibrium ?

Answer 7

The forwards and backwards reactions are occurring at the same rate
- requires a closed system
- the concentrations will remain constant

Question 8

If the forward reaction is +78kj than the type of reaction taking place is ?

Answer 8

Endothermic
Meaning to reverse the reverse reaction will be -78kj

Why? The amount of energy transferred is the same in each case
