True or False: It is recommended to use sugar cubes to sweeten lemonade because they have a low surface area.

False

Explanation:

Sugar cubes do not have a large surface area that is exposed to increase the rate of reactions with the lemonade.

Most reactions are driven by the surface area on which reactants comes in contact with. If a surface area is large enough, the reaction will proceed quite faster.

For sugars, the cubes do not have a large surface area. A low surface area will slow the reaction rate. If we turn the cube into powder or granules, more surface area is exposed and the reaction proceeds faster.
