Purpose: The purpose of this experiment is to determine how the surface area of CaCO3(s) affects the rate of reaction by measuring the volume of CO2(g) produced with time. Background: When solid reactants are mixed with liquid reactants only the particles on the surface of the solid will have direct contact‚ or collide‚ to the other liquid reactant particles. When there is more surface area there will be more solid particles exposed to collide
