Question

The rate of reaction increases if the exposed surface area of the reactant is less.


  1. True

  2. False


Solution

The correct option is B

False


There are many factors which affect the rate of a reaction. A surface area of solids is one such factor which affects the rate of the reaction. The rate of reaction increases if the exposed surface area of the reactant is more. For example, the rate of the reaction will be more if we use a powdered form of marble with dilute HCl instead of using a marble piece.
