Rate

Question 1

Increasing temperature

Answer 1

Increases kinetic energy of particles

Which will increase amount of successful collisions

And therefore rate of reaction increases

Question 2

Increasing surface area

Answer 2

Increases number of reactant particles that are exposed

Which will increase the frequency of collisions

Increasing rate of reaction

Question 3

Increasing concentration

Answer 3

Increases number of particles in a given volume

Which will increase the frequency of collisions

And increase rate of reaction

Question 4

Collision theory

Answer 4

Particles must collide with each other in the right direction to react

Collisions must have enough energy to overcome the activation energy

Question 5

Increasing pressure

Answer 5

Increases number of particles in a given volume

Increasing frequency of collisions and no. Successful collisions

Increasing rate of reaction

Question 6

Using a catalyst

Answer 6

Lowers Ea and particles require less energy to successfully collide

Which will increase amount of successful collisions

Increasing rate of reaction
