C8 Rates and equilibrium

Question 1

Explain, in terms of particles, why the rate of reaction increases when the temperature increases

Answer 1

• Particles gain more energy and therefore more faster
• There are more collisions between particles and more of the collisions are successful

Question 2

What does equilibrium mean?

Answer 2

The rate of the forward reaction and the rate of the backward reaction are equal

Question 3

What is the yield in a reaction?

Answer 3

The amount of product made

Question 4

Factors affecting equilibrium

Answer 4

• The concentration of reactants
• Temperature
• Pressure
