Question

State whether true or false :
The greater the surface area for the same volume, the lesser would be the reactivity.

• A. True
• B. False

Answer 1

The correct option is B False

Greater the surface area, greater are the reaction rates.
This is because reaction occurs when particles in gas/liquid collide with the particles in solid. Increasing the surface area of solid increases the chances of collision taking place. So, reaction rate increases as the surface area is increased.
