Investigating a Change in Surface Area

  • To measure the effect of surface area on the rate of reaction
  • To consider fair testing and accuracy in my method
  • To justify why increasing the surface area increases the rate of reaction

Increasing Surface Area in Calcium Carbonate

To increase the surface area of calcium carbonate we can use smaller chips and even crush it into a powder.
