Effect of Surface Area on Reaction Rates
What you need to know
Explain the effects on rates of reaction of changing the size of solid reactant pieces in terms of the surface area to volume ratio.
Understand that breaking a solid reactant into smaller pieces increases the contact area with solutions, thereby increasing the rate of reaction for a given mass.
Calculate the surface areas and volumes of cubes to model the effect of particle size.
Use proportionality when comparing factors that affect the rate of reaction.
