Question 1

What are the 3 conditions of a reversible reaction

Answer 1

Only occurs in closed systems
The concentration of substance remains constant
Rate of forwards reaction equals rate of backwards reaction(Dynamic equilibrium)

Question 2

Give 3 reasons why the product may be released before achieving maximum equilibrium(3)

Answer 2

1)Equilibrium will shift to the right
2)Removal of product decreases the rate of the backwards reaction
3) unreacted reactants can be recycled

Question 3

Why does increasing the temperature increase the rate of reaction

Answer 3

A greater proportion of the molecules have more energy that the activation energy

Question 4

Why does increasing pressure increase rate of reaction

Answer 4

Frequency of collisions increases as there are more molecules per unit volume
