GCSE Rates of Reaction Summary

The minimum amount of energy required for a reaction is called

• Successful energy
• Collision energy
• Activation energy
• Minimum energy

Which factor does not affect rate of reaction?

• Time
• Concentration
• Pressure
• Temperature

When is this reaction complete?

• 6 minutes
• 5 minutes
• 7 minutes
• 3 minutes

This experiment shows how we can measure rate by

• Volume of gas consumed
• Change in Mass
• Temperature change
• Volume of gas produced

Increasing the concentration will

• Increase the number of particles in a fixed volume
• Decrease the number of particles in a fixed volume 
• Increase the volume of a fixed number of particles
• Decrease the volume of a fixed number of particles

Increasing the surface area of a solid reactant will affect

• the energy of the particles
• the frequency of collisions
• both the energy and frequency of collisions
• Neither

Increasing the pressure will affect

• Neither
• the energy of the particles
• both the energy and frequency of collisions
• the frequency of collisions

Increasing the temperature will affect

• both the energy and frequency of collisions
• Neither
• the energy of the particles
• the frequency of collisions

Adding a catalyst will affect

• both the energy and frequency of collisions
• the energy of the particles
• the frequency of collisions
• Neither

Catalysts work by...

• Removing activation energy
• Increasing the activation energy
• Lowering the activation energy
• Halving the activation energy
