WebSep 8, 2024 · Whether the back reaction has an effect on the net rate of dissolution depends on what is in the water before you add the solid calcium carbonate. It also depends on how much you add. Given two specific scenarios (the entire composition of the system), a quantitative answer would be possible. Share Improve this answer Follow WebConcentration can affect the rate of reaction by changing the number of reactant molecules present. The more reactant molecules there are, the greater the number of collisions that will occur between them and the faster the rate of reaction is. As concentration increases, the rate of reaction increases. trust onyx
