Answer:

The large lump of CaCO3 has a small surface area relative to the same mass of powderedCaCO3. This means that more particles of CaCO3 will be in contact with HCl in thepowdered CaCO3 than in the lumps. As a result, there can be more successful collisions per unit time and the reaction of powderedCaCO3 is faster
