Increasing temperature
Increases kinetic energy of particles Which will increase amount of successful collisions And therefore rate of reaction increases
Increasing surface area
Increases number of reactant particles that are exposed Which will increase the frequency of collisions Increasing rate of reaction
Increasing concentration
Increases number of particles in a given volume Which will increase the frequency of collisions And increase rate of reaction
Collision theory
Particles must collide with each other in the right direction to react Collisions must have enough energy to overcome the activation energy
Increasing pressure
Increases number of particles in a given volume Increasing frequency of collisions and no. Successful collisions Increasing rate of reaction
Using a catalyst
Lowers Ea and particles require less energy to successfully collide Which will increase amount of successful collisions Increasing rate of reaction
