1. Adding a catalyst to a reaction mixture.
: Less chance of a reactant collision in the same volume.
: Increases the surface area for the reaction.
: Increases the chance of a 'fruitful' collision between gas particles.
: It speeds up a reaction but doesn't change in the end.
: Local decrease in reaction rate.
2. Decreasing the concentration of a reactant.
: Less chance of a reactant collision in the same volume.
: Increases the surface area for the reaction.
: Increases the chance of a 'fruitful' collision between gas particles.
: It speeds up a reaction but doesn't change in the end.
: Local decrease in reaction rate.
3. Breaking up the lumps of solid reactant.
: Less chance of a reactant collision in the same volume.
: Increases the surface area for the reaction.
: Increases the chance of a 'fruitful' collision between gas particles.
: It speeds up a reaction but doesn't change in the end.
: Local decrease in reaction rate.
4. Increasing the pressure of reactants.
: Less chance of a reactant collision in the same volume.
: Increases the surface area for the reaction.
: Increases the chance of a 'fruitful' collision between gas particles.
: It speeds up a reaction but doesn't change in the end.
: Local decrease in reaction rate.
5. No stirring of a solid reactant in a solution reaction.
: Less chance of a reactant collision in the same volume.
: Increases the surface area for the reaction.
: Increases the chance of a 'fruitful' collision between gas particles.
: It speeds up a reaction but doesn't change in the end.
: Local decrease in reaction rate.
