Essential Chemistry for IGCSE - Rate Of Reaction (Section 4 - No. 14)
What is the role of surface area in reaction rates?
Surface area is unrelated to reaction rates.
Increasing surface area decreases the reaction rate.
Increasing surface area increases the reaction rate.
Surface area has an unpredictable effect on reaction rates.
Explanation
A greater surface area allows for more contact between reactants, leading to more frequent collisions and a faster reaction.
