Solid calcium carbonate (CaCO₃) reacts with hydrochloric acid (HCI) to form carbon dioxide, water, and calcium chloride (CaCl), according to this equation:
CaCO₃(s) + 2HCl(aq) - CaCl₂(aq) + H₂O(aq) + CO₂(g)
Which of these actions would increase the rate of this reaction?
a) using a more concentrated HCl solution
b) crushing the CaCO₃ into a fine powder
c) increasing the pressure on the system
