Solution

  1. The rate of a chemical reaction depends upon the size of the reactant particles taking part in the reaction.
  2. Smaller the size of the reactant particles, higher is the rate of reaction.
  3. The size of reactant particles is more in pieces of Shahabad tile as compared to powder of Shahabad tile.
  4. When HCl is added to pieces of Shahabad tile, the CO2 effervescence is formed slowly. However, when HCl is added to Shahabad powder, the CO2 effervescence is formed at a faster rate.
    Hence, it takes time for pieces of Shahabad tile to disappear in HCl, but its powder disappears rapidly.
