Give four examples of factors that could speed up a chemical reaction?

Answer 1

Things that could speed up a chemical reaction include, temperature, nature of the reactants, catalysts, surface area, and concentration. Which of these may apply to your experiment will almost always vary depending on the type of experiment.

Answer 2

1. Increase in temperature: Higher temperature provides reactant molecules with more energy, leading to more frequent and energetic collisions.
2. Increase in concentration: Higher concentration of reactants results in more reactant molecules being available to collide and react.
3. Catalysts: Catalysts provide an alternative reaction pathway with lower activation energy, speeding up the reaction without being consumed.
4. Surface area: Increasing the surface area of reactants (e.g. by grinding them into smaller particles) allows for more collisions to occur simultaneously, speeding up the reaction.
