rate of reaction

Question 2

How do you work out mean rate of reaction

Answer 2

Quantity of reactants used or quantity of products formed
————
Time taken

Question 3

Factors that affect rate of reaction

Answer 3

Temperature
Surface area
Concentration/pressure
Catalyst

Question 4

What does the catalyst do to improve rate of reaction

Answer 4

Lowers activation energy by providing alternative route

Question 5

Collision theory

Answer 5

For particles to react they have to collide with each other with sufficient energy

Question 6

What is rate of reaction based on(2)

Answer 6

Amount of energy the particles have
Frequency of collision

Question 7

If there’s more of the reactant what way does equilibrium lie

Answer 7

Equilibrium lies on the left

Question 8

If there’s more product than reactant what way does equilibrium lie

Answer 8

The right

Question 9

What is le Chatelier principle

Answer 9

Change the conditions of a reversible reaction the position of equilibrium will shift to try and counteract the change

Question 10

If we reduce pressure what side does equilibrium shift to

Answer 10

Side with more molecules

Question 11

If we increase pressure what side does equilibrium shift to

Answer 11

Side with less molecules
