How can a chemical change be sped up?

1 Answer

By chemical "change", I believe you meant chemical Reaction.

A chemical reaction can be sped up by many factors. Here's a list of the most common ways to speed up a chemical reaction:

  • Increase the temperature in Endothermic reactions (Reactions that absorb energy, or become cold)
  • Decrease the temperature in Exothermic reactions (Reactions that release energy, or become hot)
  • Add a catalyst (A substance that reduces activation energy, speeding up the reaction)
  • Increase the concentration of reactants
  • Increase the concentration of catalysts
  • Increasing the surface area of reactants (If it's a solid, try crushing it)

Sorry if I didn't get what you meant by chemical Change, but hope Reactions is what you meant! :)
