Reaction rates. Image 1 of 2. Large limestone rock (calcium carbonate,CaCO3) reacting slowly with dilute acid to produce carbon dioxide gas bubbles. Here,the relatively small surface area of the limestone results in a slow reaction. This is an acid-base reaction,where calcium carbonate (the base) reacts with the acidic hydrogen (H+) to form aqueous calcium ions & carbonic acid (H2CO3). This acid is unstable,and rapidly decomposes to form carbon dioxide (CO2) & water (H2O): 1) CaCO3 H2O For a fast reaction rate,see image A500/298 | |
