Problem: Why might you want to heat a reaction? More than one answer may be correct. a) To decrease the rate of the desired reaction. b) To overcome the activation energy for the reaction. c) To increase the rate of the reaction d) To evaporate the solvent more quickly. e) To increase the solubility of the reagents.

Common factors affecting the rate of a reaction:

  • temperature: ↑T →↑rate 
  • concentration: ↑concentration → ↑ rate
  • particle size: ↑particle size (↑surface area) ↑ rate 


Adding heat = increasing T:

  • ↑T → ↑KE → ↑energy
  • ↑T → causes evaporation of liquids (T > boiling point)
  • ↑T → ↑solubility (except for gases)
