Reaction Rate Basics

Reaction Rates are affected by a few things. Without telling them the point, the students had a quick demo where they had to dissolve sugar cubes the fastest. 

The things that speed up reactions are:
  • Temperature - warmer is faster
  • Surface Area - small pieces have more surface area
  • Concentration - the more water, the faster sugar will dissolve
  • Catalyst - lowers the activation energy and speeds up the reaction
  • Agitation - shaking or stirring increases the frequency of collisions.
