1. Increasing the temperature.
: It results in more collisions of the same energy.
: It slows a reaction down.
: Lowers the activation energy.
: This only slows down gaseous reactions.
: Increases the kinetic energy of the particles.
2. Adding a catalyst to a reaction mixture.
: It results in more collisions of the same energy.
: It slows a reaction down.
: Lowers the activation energy.
: This only slows down gaseous reactions.
: Increases the kinetic energy of the particles.
3. Increasing the concentration of a reactant.
: It results in more collisions of the same energy.
: It slows a reaction down.
: Lowers the activation energy.
: This only slows down gaseous reactions.
: Increases the kinetic energy of the particles.
4. Using bigger lumps of solid reactant.
: It results in more collisions of the same energy.
: It slows a reaction down.
: Lowers the activation energy.
: This only slows down gaseous reactions.
: Increases the kinetic energy of the particles.
5. Decreasing the pressure of reactant.
: It results in more collisions of the same energy.
: It slows a reaction down.
: Lowers the activation energy.
: This only slows down gaseous reactions.
: Increases the kinetic energy of the particles.
